| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* lsof: correct check for symbolic linkThomas De Schampheleire2013-06-271-3/+6
| | | | | | | | | | | | | | | | | | | | Busybox lsof used the d_type field of a 'struct dirent' to verify whether the entry is a symbolic link. This field, however, is not portable. On at least one board [1] I have seen, that field is 0, and the check fails even though the entry is a link. The explicit check for a symbolic link is really only needed to skip the default directory entries '.' and '..'. The directory /proc/<pid>/fd/ should not contain anything else but these two and symbolic links. With these assumptions, this patch replaces the explicit link check with a basic check for '.' and '..' (and any hidden file). In the unlikely case that there are other file types, xmalloc_readlink() will return NULL, and we can skip the entry. [1] A MIPS-based board with glibc 2.9, Linux 2.6.32.27.

* pgrep: fix -x optionBernhard Walle2013-02-281-1/+1
| | | | | | | | | | | | | | Because when -x is used (exact match), then we cannot compile the regular expression with REG_NOSUB. The manual page regcomp(3) states in section "Byte offsets": Unless REG_NOSUB was set for the compilation of the pattern buffer, it is possible to obtain substring match addressing information.
