Denys Vlasenko	60ca834358	ash: [MEMALLOC] Add pushstackmark Upstream commit: Author: Herbert Xu <herbert@gondor.apana.org.au> Date: Sat Oct 6 00:45:52 2007 +0800 [MEMALLOC] Add pushstackmark This patch gets rid of the stack mark tracking hack by allocating a little bit of stack memory if we're at risk of planting a stack mark which may be grown later. To do this a new function pushstackmark is added which lets the user pick a bigger amount to allocate since some users do that anyway after setting a stack mark.

Denys Vlasenko	215b0ca6e4	hush: fix a bug in FEATURE_SH_STANDALONE=y config. Closes 9186 Run this in a "sh SCRIPT": sha256sum /dev/null echo END sha256sum is a NOEXEC applet. It runs in a forked child. Then child exit()s. By this time, entire script is read, and buffered in a FILE object from fopen("SCRIPT"). But fgetc() did not consume entire input. exit() lseeks back by -9 bytes, from <eof> to 'e' in 'echo'. (this may be libc-specific). This change of fd position is shared with the parent! Now parent can read more, and it thinks there is another "echo END". End result: two "echo END"s are run. Fix this by _exit()ing instead.

Kylie McClain	40eea690c7	Fix compiling with musl's utmp stubs This patch fixes compiling busybox with FEATURE_UTMP and _WTMP enabled. musl, while not really support utmp/wtmp, provides stub functions, as well as variables such as _PATH_UTMP, so that programs using utmp or wtmp can still compile fine. My reasoning for this patch is that on Exherbo, I'm currently trying to get us to be able to use the same busybox config file for both glibc and musl systems, using utmp/wtmp on systems that support it, and using the stubs on musl without needing two different configs. As of latest musl git, it provides all utmp functions needed; 1.1.12 doesn't, but I sent a patch to Rich to add the utmp{,x}name functions expected to exist, which was merged into musl upstream.

Ron Yorston	0e056f7e9e	ash: remove parsebackquote flag Commit 503a0b8 from git://git.kernel.org/pub/scm/utils/dash/dash.git by Herbert Xu says: >The parsebackquote flag is only used in a test where it always has the >value zero. So we can remove it altogether. The first statement is incorrect: parsebackquote is non-zero when backquotes (as opposed to $(...)) are used for command substitution. It is possible for the test to be executed with parsebackquote != 0 in that case. The test is question checks whether quotes have been closed, raising the error "unterminated quoted string" if they haven't. There seems to be no good reason to allow unclosed quotes within backquotes. Bash, hush and dash (after commit 503a0b8) all treat the following as an error: XX=`"pwd` whereas BusyBox ash doesn't. It just ignores the unclosed quote and executes pwd. So, parsebackquote should be removed but not for the reason stated. function old new delta parsebackquote 1 - -1 readtoken1 3222 3182 -40 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 0/1 up/down: 0/-41) Total: -41 bytes Signed-off-by: Ron Yorston <rmy@frippery.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2015-07-13 03:50:27 +02:00

Colin Watson	3963d943f8	ash: refresh stack pointers after makestrspace in rmescapes Without this, rmescapes sometimes returns random garbage while performing parameter expansions such as ${foo#bar}, in the event that the allocation of r happens to need to reallocate the stack and hence invalidate str and p. I'd love to provide a test case but unfortunately it's dependent on exact stack layout, so I don't have anything simpler than the situation described in https://bugs.launchpad.net/ubuntu/+source/partman-base/+bug/527401/comments/23 which involved a sequence of foo="${foo#*, }" expansions on a long string inside our RAID configuration tool. The same fix has been in dash since 2007-09-26, contributed by Roy Marples <uberlord@gentoo.org>. I actually came up with it independently almost to the character, but then synced it up with the variable naming used in dash when I noticed that change afterwards.
