This file contains a list of specific bugs that have been fixed, and patches
that have been applied in released versions. Please see the NEWS file for
a summary of the major changes, and the ChangeLog file for a comprehensive
listing of all changes made to the code.
*5.7.3*
snmplib:
- Fixed crash when MD5 hash is not supported by OpenSSL.
- Fixed parsing of sequences. Don't overwrite 'data' variable, it's
used when parsing bulk responses.
- [BUG 1267 ]: snmplib: register_mib_context() fix for read-only
variables This is a slightly modified version of a patch from
Harsha Shivanna.
snmp:
- Usm-dh-objects-mib: Avoid triggering an assert statement in
netsnmp_ready_monotonic() The cache timeout for
snmp-usm-dh-objects-mib is -1. Any cache timeout value < 0 disables
caching. However, strictly negative values trigger the assert
statement in netsnmp_ready_monotonic(). Avoid triggering that
assert statement.
- Fixed monitoring based on non-delta trigger. snmpd crashed wit
following snmpd.conf: monitor -s -D -r 10 -e LOGMATCH -o
logMatchCurrentCount "Log Match" != logMatchCurrentCount logmatch
LoginFailure1 /var/log/secure 10 su: .*fail.* The reason was
unitialized variable sysUT_var in mteTrigger_run(), it was filled
only if the trigger was delta-valued, while its value was used for
all triggers. With this patch, sysUT_var is filled for all code
branches where it is needed.
snmpd:
- Add a missing function declaration
- Added btrfs support to hrFSTable
- Correct the size of of the EXAMPLEIPADDRESS value on L64 hosts
- Fixed crash in UCD-SNMP-MIB::extTable snmpd crashed when the
command to execute had no arguments, i.e. extend->args was NULL.
- Fixed value of UCD-SNMP-MIB::extCommand to contain full command
line. MIB description of UCD-SNMP-MIB::extCommand suggests it
should contail full command line. Also in Net-SNMP 5.3.2.2, whole
command line was shown.
- Make it possible to use NUL characters in the indices for
snmpTargetAddrTable
- PATCH 2472: from Sunil: don't use HBKT as heartbeat interval in
SCTP-MIB::sctpAssocTable.
- Remove some unused includes
- Show Linux kernel threads in hrSWRunTable.
- Use 0 for the ignored numvars argument to netsnmp_register_mib The
numvars argument of netsnmp_register_mib is ignored if the var
argument is NULL. In order to unify this use of it with all other
ones, change it from 1 to 0
- SECURITY: a denial of service attack vector was discovered on
the linux implementation of the ICMP-MIB. This release fixes
this bug and all users are encouraged to update their SNMP
agent if they make use of the ICMP-MIB table objects.
- PATCH: 1275: from Viliam Púčik: fixed Perl trap handler when
processing trap with empty community string.
snmpd, snmptrapd and apps:
- Make ENV_SEPARATOR_CHAR configurable
snmptrapd:
apps:
- Stop agentxtrap from accessing the persistent configuration This is
needed to prevent moaning about not beeing allowed to write those
files due to bad permissions.
- Stop using snmp_perror when logging after functions that don't set
snmp_errno.
building:
- Make the -without options to rpmbuild work
- Avoid duplicate and trailing spaces in the dependency files.
documentation:
- From "Eric S. Raymond": Correct man page markup problem Ambiguous
or invalid backslash. This doesn't cause groff a problem. but it
confuses doclifter and may confuse older troff implementations.
perl:
- BUG: 2402: Add support for SNMPv3 traps
python:
- Fixed IPADDRESS size on 64bit systems.
- Fixed returning of empty strings. Varbind type (SNMP_NOSUCHOBJECT
etc.) should be used to detect errors instead of length of the
variable - it can be empty string.
- [PATCH 1239]: Fix memory leak
testing:
- Make sure Test::Harness is of at least version 1.21 Test::Harness
1.21 is the first version that implements TAP v12 which allows
putting the header (1..N) after the tests and since our tests
utilize that we should make sure that the test runner supports it.
AIX:
- Make tcp-mib build
- Make udp-mib build
Linux:
- BUG: 2238: Add libnl3 support
- RESOURCES-MIB, hrSWRun table: Parse /proc/<pid>/stat correctly on
Linux This issue was reported by Vincent Bernat
<vincent.bernat@dailymotion.com>. See also
http://sourceforge.net/p/net-snmp/patches/1257/.
Win32:
- Modified patch from Bart Van Assche to improve cygwin building
- Perl: BUG: 2488: Avoid "Free to wrong pool" error
- Perl: BUG: 2488: Avoid "Free to wrong pool" error" This reverts
commit b2725964bde921b6285e3a59a512552cae0a0ca5.
Windows:
- Add multihoming support On Windows Vista / Windows Server 2008 and
later it is possible to add multihoming support by using the
IP_PKTINFO socket option. Conflicts:
snmplib/transports/snmpUDPBaseDomain.c
- Make winExtDLL work on 64-bit Windows systems
- Port batch build infrastructure to Visual Studio 2010 and later
From Visual Studio 2010 on it is no longer possible to specify
include or library directories globally - these have to be
specified per project. Hence two additional menu entries in
build.bat that allow to specify these directories.
- Ported ucd-snmp/dlmod to MinGW / MSVC
MinGW:
- Port T005table_dataset_cagentlib.c to MinGW
unspecified:
- Added simfs (OpenVZ filesystem) to hrStorageTable and hrFSTable.
- Upport new MIB structures and MFD rewrites under Darwin
- [BUG 2470]: Accept 65535 as a valid IPv6 port number
- [BUG 2476]: snmpd fails to start on AIX On an AIX system there is
no <kvm.h> header file nor do the /dev/dmem or /dev/drum devices
exist and hence DMEM_LOC is not defined. Avoid that init_kmem()
fails in that case.
- [BUG 2568]: Avoid that file descriptors above FD_SETSIZE trigger
abort()
*5.7.2*
snmplib:
- Add Doxygen-style function header for
netsnmp_register_default_target() and
netsnmp_clear_default_target().
- Add netsnmp_setenv().
- Avoid that system clock changes (e.g. by ntpd) affect code that
needs relative time Make sure that the range of the SNMPv3 variable
snmpEngineTime is 0..2147483647 on all supported systems instead of
0..42949672 on some systems (i.e. wraparound after 497 days) Add
netsnmp_get_monotonic_clock(), netsnmp_set_monotonic_marker(),
netsnmp_ready_monotonic(), netsnmp_get_agent_runtime()
- Avoid that system clock changes (e.g. by ntpd) affect code that
needs relative time Make sure that the range of the SNMPv3 variable
snmpEngineTime is 0..2147483647 on all supported systems instead of
0..42949672 on some systems (i.e. wraparound after 497 days) Add
netsnmp_get_monotonic_clock(), netsnmp_set_monotonic_marker(),
netsnmp_ready_monotonic(), netsnmp_get_agent_runtime() Deprecate
atime_diff(), atime_newMarker(), atime_ready(), atime_setMarker(),
marker_tticks(), netsnmp_marker_uptime(), netsnmp_timeval_uptime(),
timeval_tticks(), uatime_diff(), uatime_hdiff() and uatime_ready().
- Avoid waiting indefinitely if a session has timeout zero
- Declare "type" argument of se_store_list() / se_store_slist() /
se_store_enum_list() const
- Make it explicit that MAX_SUBID is an unsigned constant

- Reduce overhead of config file parsing
- Remove obsolete snmp_get_fd_for_session() declaration
- Separate out the cmesg buffer size
- Set the rpath for libperl.so in libnetsnmpmibs.so such that the
dynamic linker can find libperl.so without requiring the user to
modify the dynamic linker settings. This change in
agent/Makefile.in is necessary on the 5.5 branch and later but not
on the 5.4 branch. That is because the 5.4 branch uses an older
version of libtool that propagates the rpath of dependent
libraries. This is called inter-library dependency tracking in the
libtool manual. This functionality is present in libtool version 1
but not in libtool version 2. For more background information about
dynamic libraries and rpaths, see also the document with the title
"RpathIssue" on the Debian wiki
(http://wiki.debian.org/RpathIssue).
- Simplify implementation of functions manipulating 64-bit numbers.
- Simplify the se_store_enum_list() implementation
- Use SNMP_ALLOC_TYPEDEF to allocate transports in order to avoid the
separate call to memset.

- Disable the support for integer64 in pass scripts if compiling
without opaque-special-types.
- Factor out asc2bin and bin2asc. Add a netsnmp_internal_ prefix to

- Fixed UCD-SNMP-MIB::systemStats after 30 days of uptime. After 30
days, values from /proc/stat (on Linux) can get bigger than 32bits
and snmpd calculations might render counters like ssCpuUser
negative or zero, while the real value is higher. Therefore the
counters should be tracked as the largest integer available.

- IF-MIB::ifType: Report type "infiniband (199)" for InfiniBand
interfaces instead of type "other (1)".
- Init_agent() + init_kmem(): Return an error value instead of
invoking exit() if access to kernel virtual memory is denied
- Make the configuration of the dlmod module fail rather than
generate a dummy module if the dlopen function isn't available.

- Pass_persist: Fixes a race condition introduced in commit
31fa07cd9ffde46d41d2b5838c3fc4d01548bfb5. The following race
condition could happen: - A system call fails and errno is set
accordingly by the C library. - SIGCHLD handler invokes a system
call that fails and hence overwrites errno. - SIGCHLD handler
leaves. - original context checks errno and finds the value from
the system call invoked by the SIGCHLD handler instead of the
system call that failed originally. Other fixes included in this
patch: - Renamed deinit_pass_persist() into shutdown_pass_persist()
such that this function gets called during agent shutdown. - Made
sure that shutdown_pass_persist() is called by the Windows
snmpd.exe too. - Windows: avoid calling
CloseHandle(INVALID_HANDLE_VALUE). - Windows: avoid that closing a
pass_persist pipe triggers a crash. - Windows: pass_persist: close
handles of finished processes.

- Perl: Make sure that the constant SNMP_DEFAULT_RETRIES is
recognized. SNMP module: Add constants
NETSNMP_CALLBACK_OP_RECEIVED_MESSAGE and
NETSNMP_CALLBACK_OP_TIMED_OUT. When the Net-SNMP Perl modules are
built on Windows with MSVC or MinGW it is possible that each these
are linked with another version of the MSVC runtime library than
the Perl interpreter itself. In that case the "errno" variable used
inside .xs source files is another variable than the $! variable in
.pm files. Or: assignments to "errno" in a .xs file do not modify
the "$!" Perl variable This patch avoids using "errno" by modifying
the different constant() functions such that these return a
two-element array instead of returning a scalar and setting errno.

- Added macro netsnmp_static_assert().
- Added netsnmp_mib_handler.data_clone, a function pointer that
defines how to clone netsnmp_mib_handler.myvoid. Must be defined if
and only if data_free is set. The function netsnmp_handler_dup()
does now clone MIB handler private data if data_clone() is set.
Previously after duplicating a MIB handler and unregistering one of
the two MIB handlers, the private data pointer (myvoid) of the
other became a dangling pointer. Note: addition of
netsnmp_mib_handler.data_clone is an ABI change.
- Added snmp_sess_session_lookup().
- Added the function netsnmp_check_definedness(), which helps to find
the cause of undefined value errors as reported by Valgrind.
- Avoid that Valgrind complains about uninitialized data for the
buffers returned by netsnmp_callback_recv() and
netsnmp_callback_hook_build().
- Be const correct over calls to str* functions.
- Changed the argument type of debug_register_tokens() from char *

- Correct the extern "C" declarations to be consistent. Remove
commented out code.
- Fenner: fix sending of UDP responses from multihomed agents. Try to
send the response as it was before Net-SNMP 5.6 (assuming the
appropriate request was unicast) and only if it fails try to set
if_index (the request must be broadcast).
- Fixed bugs in asn_parse_unsigned_int64(),
asn_build_unsigned_int64(), asn_parse_signed_int64() and
asn_build_signed_int64(). Most but not all of these bugs were
specific to 64-bit systems. Fixes bug #3093199.

- Fixed a memory leak in snmp_free_session().
- [BUG 3184697]: Don't reference internal MD5 when it's explicitly
disabled
- [BUG 3234754]: Ensure old f_create_from_tstring hook is initialized
to NULL
- [BUG 3264852]: Recognise missing report types
(snmp{Unavailable,Unknown}Contexts,snmpUnknownPDUHandlers)
- _mibindex_add() no longer reads past the end of the dynamically
allocated array _mibindexes.
- [BUG 3151845]: fix multiple registrations of snmp transport handler
snmp:
- patch: 3096725: sysORTable registation for notification log mib
original patch fixed several issues, other parts applied earlier
snmpd:
- Add missing function declaration
- Added functions netsnmp_handler_owns_tabreq(),
netsnmp_registration_owns_tabreq(), netsnmp_iterator_clone().
Exported netsnmp_table_registration_info_clone().
- Added functions netsnmp_handler_owns_tabreq(),
netsnmp_registration_owns_tabreq(), netsnmp_iterator_clone().
Exported netsnmp_table_registration_info_clone(). Modified
netsnmp_iterator_delete_table() such that it frees the table
registration information stored in a table iterator too. Modified
netsnmp_get_table_iterator_handler() such that the table iterator
passed to this function is freed when the associated handler is
freed. Restored the behavior of netsnmp_get_table_handler() to that
of r19449, that is, not setting up the data_free pointer because
not all callers of netsnmp_get_table_handler() expect that table
registration information is freed when the associated handler is
freed.
- Added netsnmp_get_table_iterator2().
- Added netsnmp_get_table_iterator2(). Added
netsnmp_register_table_iterator2().
- Added netsnmp_get_table_iterator2(). Added
netsnmp_register_table_iterator2(). Added
netsnmp_handler_owns_iterator_info().
- Added netsnmp_get_table_iterator2(). Added
netsnmp_register_table_iterator2(). Added
netsnmp_handler_owns_iterator_info(). Fixed leak-at-exit triggered
by snmpNotifyTable.
- Added netsnmp_get_table_iterator2(). Added
netsnmp_register_table_iterator2(). Added
netsnmp_handler_owns_iterator_info(). Fixed leak-at-exit triggered
by snmpNotifyTable. Fixed leak-at-exit triggered by
snmpTargetAddrTable. Also, restored backwards compatibility of
netsnmp_register_table_iterator().
- Added netsnmp_register_watched_instance2(),
netsnmp_register_watched_scalar2(), netsnmp_clone_watcher_info()
and netsnmp_owns_watcher_info(). See also the Doxygen comments for
more info.
- Added netsnmp_unregister_auto_data_table().
- Added reference count in the netsnmp_baby_steps_modes data
structure and made sure that this data structure is automatically
freed when the handler that owns it is unregistered.
- Added snmp_sess_session_lookup(). Call shutdown_master_agent() and
shutdown_agent() during shutdown.
- Added snmp_sess_session_lookup(). Call shutdown_master_agent() and
shutdown_agent() during shutdown. The function clean_subtree() does
no longer trigger double frees and invalid memory reads. Note: this
function was already wrong at the time it was introduced (patch
#724925 / r8531, July 2003).
- Added snmp_sess_session_lookup(). Call shutdown_master_agent() and
shutdown_agent() during shutdown. The function clean_subtree() does
no longer trigger double frees and invalid memory reads. Note: this
function was already wrong at the time it was introduced (patch
#724925 / r8531, July 2003). Removed a comment in
netsnmp_handler_free() that is now obsolete because of the
clean_subtree() changes.

shutdown_agent() during shutdown. The function clean_subtree() does
no longer trigger double frees and invalid memory reads. Note: this
function was already wrong at the time it was introduced (patch
#724925 / r8531, July 2003). Removed a comment in
netsnmp_handler_free() that is now obsolete because of the
clean_subtree() changes. Modified netsnmp_deregister_agent_nsap()
such that it never examines sessions that already have been closed.
It is for this change that it was necessary to introduce the new
function snmp_sess_session_lookup().
- Added the functions netsnmp_duplicate_variable() and
netsnmp_cache_handler_owns_cache().
- Added the functions netsnmp_duplicate_variable() and
netsnmp_cache_handler_owns_cache(). Memory allocated by
netsnmp_register_old_api() for storing SNMP variables is now freed
when the associated handler is unregistered.
- Added the functions netsnmp_duplicate_variable() and
netsnmp_cache_handler_owns_cache(). Memory allocated by
netsnmp_register_old_api() for storing SNMP variables is now freed
when the associated handler is unregistered. Callback function data
deallocation does no longer free the memory allocated for the
AgentX session - the memory that was allocated for AgentX sessions
is now deallocated just as that for any other session. This fixes a
leak-at-exit.

deallocation does no longer free the memory allocated for the
AgentX session - the memory that was allocated for AgentX sessions
is now deallocated just as that for any other session. This fixes a
leak-at-exit. Notify filter table: Callback function data
deallocation does no longer free the data in *
*snmpNotifyFilterTable_if_ctx.container - this is now done by
shutdown_snmpNotifyFilterTable() and
- Automatically free the private data structure allocated by
netsnmp_container_table_handler_get().
- Builds with most recent MinGW (having #define localtime_r).
- Count the number of users of a netsnmp_cache data structure instead
of duplicating it.
- Declare the OID argument type of MIB registration functions as
'const oid *' instead of 'oid *' since these functions do not
modify the OID.
- Do not leak the limits of scalar_group objects on shutdown.
- Extend the documentation for data_clone and data_free
- Factor out common config_add_mib statments
- Find out whether librpm is available before configuring the agent
modules because host/data/access/swinst needs symbol HAVE_LIBRPM.
As a result, configure has to be run only once instead of twice to
enable the hrSWInstalled table on systems that have librpm.
- Fixed a double free at exit that was triggered by cleaning up the
data structures used for embedded Perl support.
- Fixed a year-2038 bug in the implementation of ipRouteTable.
- Introduced netsnmp_pid_t.
- MIB-specific leak-at-exit fixes.
- Make it possible to copy watched data items without memory leaks.
- Make the setting of the argvrestart* variables optional on
USING_UTIL_FUNCS_RESTART_MODULE.
- Make the setting of the argvrestart* variables optional on
USING_UTIL_FUNCS_RESTART_MODULE. Remove util_funcs/restart from the
requirement sets of util_funcs and default_modules.
- Make the setting of the argvrestart* variables optional on
USING_UTIL_FUNCS_RESTART_MODULE. Remove util_funcs/restart from the
requirement sets of util_funcs and default_modules. Add
util_funcs/restart to the requirement set of ucd-snmp/versioninfo.
- Patch 3141462: from fenner: fix agentx subagent issues with
multiple-object requests
- Patch from Niels to fix VACM persistant storage.
- Remove unused variable cmp
- Remove util_funcs/Exit from the requirement sets of util_funcs and
default_modules.
- Remove util_funcs/Exit from the requirement sets of util_funcs and
default_modules. Never use Exit to terminate the agent.
- Removing the last cache via netsnmp_cache_remove() does no longer
trigger a crash.
- Update the length of sysObjectID as well as the data when it is set
from a configuration file.
- Use the same autoconf symbol to decide both if strcasecmp should be
declared and if it should be defined.

corruption by invoking select().
- [PATCH ]: optimizations for large route tables from Stephen
Hemminger applied parts 1-3 of 4 from him (msgs to coders on
2/28/11; subject ip-forward-mib performance improvements; part 4
needs more work
- add debug for cert find hint as string/int
- add newly created/destroyed interfaces to ipv6IfTable The list of
interfaces was never refreshed, now it is reloaded every time the
table is accessed. I've also fixed a memory leak and optimized the
loading of the list a bit.
- com2sec6 directive: If configure has not found getaddrinfo(),
non-numeric IPv6 addresses do now trigger an error message.
- don't second-guess cache handler (waves hand) this is not the
function you are looking for. netsnmp_cache_is_valid() is not meant
for mib modules
- example MIB: Added shutdown function that frees all memory owned by
this MIB implementation.
- fix double free in TLS error handling
- fixed the agent writing 'looks like a 64bit wrap, but prev!=new' in
syslog when computing ipSystemStats Without the memcpy,
prev_vals->stats and new_vals->stats could get different, which
could much much later (when a counter gets bigger than 32 bits)
result in 'prev!=new' message in syslog. Typically this happens
after long time of uptime and it is very hard to reproduce.
- host/data_access/swinst_rpm: Fixed a memory leak in
netsnm_swinst_arch_init().
- host/data_access/swinst_rpm: Pass correct path to rpmdbOpen() such
that opening the database succeeds.
- host/data_access/swinst_rpm: Pass correct path to rpmdbOpen() such
that opening the database succeeds. host/data_access/swinst_rpm:
Log an error message if rpmdbOpen() fails.
- instead of relying on NETSNMP_DS_LIB_APPTYPE, break out cert table
inits to new agent cert init function, called from init_agent.
- netsnmp_cache_free(): A more detailed message is now logged when
attempting to free a cache that is still in the cache list.
- reworked hrStorageTable to support large filesystems. The
hrStorageAllocationUnits does not report real allocation unit size,
but some calculated value so hrStorageAllocationUnits *
hrStorageSize gives real size of the filesystem. This calculation
happens only when hrStorageSize is too small (32bits) for
filesystem size, e.g. filesystems larger than 8TB with 4096 bytes
block size. This calculation can be turned off by
'realStorageUnits' config option.
- skip non-AF_INET interfaces when loading ipv4 addrs
- snmpd is again single-threaded. [PATCH 2959811]: Safranek:
Reimplement Linux Netlink IPv6 prefix listener.
- Fixed memory leak in TCP-MIB tables introduced by patch #3053436.
- Fixed memory leak in TCP-MIB tables introduced by patch #3053436."
[PATCH 3053436]: from: takevos: fix: tcpConnectionTable_data_access
invalid memory access" the bug 3053436 is fixing was introduced in
r17719, and fixed in r17861.
- Use proper format specifier in debug statements for printing values
of type 'oid'.
- [PATCH 3066862]: fix the agent for comparing unsigned large indexes
of the disk and extend tables.
- fixed hrSWRunPath of swapped-out processes on Linux. fgets()
returns NULL both when /proc/PID/cmdline is empty (= swapped out)
and when the process exited after fopen(), so check
/proc/PID/status in both cases.
- fixed race condition in hrSWRunTable Treat the reads from
/proc/<pid>/* carefuly, processes can exit in the middle of
processing. (already fixed in V5-5-patches and V5-4-patches in SVN
rev. 20115, dunno why I did not patch trunk)
- patch 3131397: from takevos: huge speedups of the TCP/UDP Tables
- patch 3299384: fix INFORMs so they retry probing for an engineID.
- patch 3306476: from tinypyramids: fix memory leak in the swrun
container loading
- ucd_snmp builds again on MinGW and Cygwin.
- patch 3310250: from fenner: misc fixes for debugging output of
agentx
