2018-04-01sed: prevent overflow of length from bb_get_chunk_from_fileQuentin Rameau
This fragment did not work right: temp = bb_get_chunk_from_file(fp, &len); if (temp) { /* len > 0 here, it's ok to do temp[len-1] */ char c = temp[len-1]; With "int len" _sign-extending_, temp[len-1] can refer to a wrong location if len > 0x7fffffff.

2011-06-17libbb: split bb_get_chunk_from_file and bb_get_chunk_with_continuationDenys Vlasenko
This also moves bb_get_chunk_with_continuation into its sole user, parse_config.c. This allows to optimize both functions separately, they need to be optimized for speed. (this need was highlighted by slow modprobe caused in part by slow bb_get_chunk_with_continuation in config parser). function old new delta bb_get_chunk_from_file 7 130 +123 config_read 457 558 +101 bb_get_chunk_with_continuation 194 - -194 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 2/0 up/down: 224/-194) Total: 30 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2010-08-16*: make GNU licensing statement forms more regularDenys Vlasenko
This change retains "or later" state! No licensing _changes_ here, only form is adjusted (article, space between "GPL" and "v2" and so on). Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

This fixes problems with NULs in files being scanned, but costs +800 bytes. The same can be done to sed (TODO).

Add xmalloc_fgetline_str which does strip terminator, and use it in dpkg instead of xmalloc_fgets_str. netstat: use xmalloc_fgets_str - allows to eat strings with NULs (this fixes bug with some weird /proc/net/unix input) function old new delta xmalloc_fgets_internal - 191 +191 xmalloc_fgetline_str - 18 +18 do_info 116 120 +4 unix_do_one 451 447 -4 tcp_do_one 423 419 -4 send_tree 369 365 -4 xmalloc_fgets_str 178 15 -163 ------------------------------------------------------------------------------ (add/remove: 2/0 grow/shrink: 1/4 up/down: 213/-175) Total: 38 bytes text data bss dec hex filename 778445 832 7344 786621 c00bd busybox_old 778483 832 7344 786659 c00e3 busybox_unstripped

2007-01-11Trailing whitespace removal over entire treeDenis Vlasenko
2006-12-20less: somewhat buggy applet, but nice. Muchly reducedDenis Vlasenko
xstrdup'ing and memory consumption. Made linewrap saner. regex matching code was awful - still buggy, but not as leaky as before. Made buffer size configurable. Killed several static and on-stack buffers. Hopefully eliminated staircase effect on Ctrl-C (unable to reproduce).

2006-06-10- fix bug #887, in bb_get_chomped_line_from_file(), the last char was removedBernhard Reutner-Fischer
unconditionally, even if it was not a newline. This was apparently broken by r14254 - whitespace while at it.
