2014-10-02ntpd: don't stay at short polling intervalMiroslav Lichvar
To avoid polling servers frequently slowly increase the interval up to BIGPOLL when - no replies are received from a peer - no source can be selected - peer claims to be unsynchronized (e.g. we are polling it too frequently) When recv() returns with an error, drop code to try to continue on network errors: I'm not convinced those cases happen in real life. function old new delta recv_and_process_peer_pkt 919 838 -81 Signed-off-by: Miroslav Lichvar <mlichvar@redhat.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* on step, poll interval drops to 8.5 mins instead of 32 seconds * on total loss of all replies (no replies from any peer for last 8 requests), also drop poll interval to 8.5 mins instead of 32 seconds * on send abd recv errors, RETRY_INTERVAL is now 32 seconds, not 5 seconds * on timing out listening to reply, instead of unconditional shortening poll interval by x4, clamp it to NOREPLY_INTERVAL (512 seconds) * if a largish offset is seen, clamp nexp poll interval to 128 seconds, not 64 seconds function old new delta clamp_pollexp_and_set_MAXSTRAT - 37 +37 recv_and_process_peer_pkt 861 869 +8 poll_interval 52 48 -4 update_local_clock 762 752 -10 ntpd_main 1063 1050 -13 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 1/3 up/down: 45/-27) Total: 18 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-07-27top: fix and merge code to parse /proc/meminfoTimo Teräs
display_header() code to parse meminfo as is was buggy: - uninitialized variables were used if meminfo was not as expected - meminfo parsing failed on new kernels (3.14+) as new field 'MemAvailable' was introduced between MemFree and Buffers - shared memory was handled only for ancient kernels (2.4.x and earlier) as result Buffers and shared memory fields were shown with bogus values on current kernels. The new code does not try to parse the old style summary header, as the separated fields are always present (it saves code size). Additionally, both Shmem (2.6+) and MemShared (2.4 and earlier) fields are now parsed and summed for shared memory usage; as only one of them exists depending on kernel version. display_topmem_header() parses also meminfo so this makes it use the same code for code shrink. function old new delta display_header - 681 +681 display_topmem_process_list 465 684 +219 parse_meminfo - 189 +189 static.fields - 106 +106 static.match 132 - -132 .rodata 120254 120117 -137 display_topmem_header 513 - -513 display_process_list 1705 667 -1038 ------------------------------------------------------------------------------ (add/remove: 3/2 grow/shrink: 1/2 up/down: 1195/-1820) Total: -625 bytes Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-07-20zcip: fix link-local IP conflict detectionKen Sharp
During link-local IP resolution, if a regular ARP request is received during the ARP probe period, it will incorrectly cause a target IP conflict. This then leads to a new IP being picked unnecessarily. Per RFC 3927, section 2.2.1, we should flag a target IP conflict only if the source IP is null, the target IP matches our IP, and the source hw addr does not match our hw addr. function old new delta zcip_main 1354 1322 -32 Signed-off-by: Ken Sharp <ken.sharp@ni.com> Signed-off-by: Ben Shelton <ben.shelton@ni.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-07-04modinfo: fix module parsing with kernel >= 2.6.37David Marchand
display() function returns the length of the value we are displaying + 1. As a consequence, if we have field=value\0field=value\0field=value in the binary, then the second occurence will be skipped as ptr will miss the first character of the following field. Example trying to list aliases from ixgbe.ko on a 3.2 kernel. - In the module we have: alias=pci:v00008086d00001560sv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Asv*sd*bc*sc*i*\0 alias=pci:v00008086d00001557sv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Fsv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Dsv*sd*bc*sc*i*\0 ... - Using modinfo -F alias ixgbe returns: alias: pci:v00008086d00001560sv*sd*bc*sc*i* alias: pci:v00008086d00001557sv*sd*bc*sc*i* alias: pci:v00008086d0000154Dsv*sd*bc*sc*i* ... This problem appeared with kernel commit "modules: no need to align .modinfo strings" b6472776816af1ed52848c93d26e3edb3b17adab in 2.6.37. Fix this by not trusting display() return value but increment ptr by strlen(ptr) (the same way as depmod.c does).
