2014-07-27top: fix and merge code to parse /proc/meminfoTimo Teräs1-110/+86
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>
2014-07-25sha3: add 32-bit optimized bit-sliced implementationDenys Vlasenko1-14/+242
It is an interesting trick, but so far I only managed to make it work correctly, not to make it faster and/or smaller. The code is ifdefed out for now. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2014-07-20zcip: fix link-local IP conflict detectionKen Sharp1-16/+22
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>
2014-07-16udhcp: add PXELINUX path prefix option (code 210) definitionJeremy Kerr2-0/+3
Like d3092c99, this change adds support for the DHCP "path-prefix" option, as defined in RFC 5071. We use the string identifer "pxepathprefix". Adding this option makes string parsing in the hook scripts simpler. function old new delta dhcp_option_strings 255 269 +14 dhcp_optflags 72 74 +2 Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-07-04modinfo: fix module parsing with kernel >= 2.6.37David Marchand1-3/+4
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).

2014-07-03syslogd: make "reopen log file every second" logic work for multiple logsJoshua Judson Rosen1-6/+7
Move last_log_time from a single global to *each logFile_t* so that we can actually apply the logic to every log-file in multi-file configurations, rather than working only for the first file written in each 1-second interval and then leaving the others connected to possibly wrong files.

2014-06-30Rename INIT_LAST to INIT_FUNC to avoid confusionBartosz Golaszewski2-3/+3
We don't have an INIT_FIRST, so let's rename INIT_LAST to INIT_FUNC to imply that the function is called at program start-up. Also: the priority argument for __attribute__((constructor)) isn't used, so let's remove it.
