similar to: [PATCH 1/2] lib: info: Move common code for setting child rlimits.

After fuzzing 'qemu-img info' I found that certain files can cause the command to use lots of memory and time. Modify the command mini-library to allow us to place resource limits on subprocesses, and use these to limit the amount of space and time used by 'qemu-img info'. --- configure.ac | 3 +++ src/command.c | 53

It obscures what's really going on and is no longer necessary for the original purpose. This reverts commit d50cb7bbb4cc18f69ea1425e9f5cee9685825f95.

Hi! I wrote a small patch to enable /etc/limits support in openssh. nice thing when you don't have PAM installed.. It is based on Ultor's openssh 1.x patch (http://marc.theaimsgroup.com/?l=secure-shell&m=96427677022741&w=2) Works fine on slackware7.1. define USE_ETC_LIMITS in config.h , and compile as usual.

Dr. David Gilbert pointed out to me that the first line of the qemu -help output includes the qemu version, so we don't need to run qemu -version at all. This saves about 0.04s on the launch time when using the direct backend. --- src/launch-direct.c | 54 +++++++++++++++++++---------------------------------- 1 file changed, 19 insertions(+), 35 deletions(-) diff --git a/src/launch-direct.c

Hey, I've just updated the FreeBSD dovecot port to the 0.99.4 beta release, the following patch was needed as FreeBSD has setrlimit(2) but does not define RLIMIT_AS (I believe). I switched the code the require both, alternatively find a parallel option in the FreeBSD setrlimit(2) manual page. ( http://www.freebsd.org/cgi/man.cgi?setrlimit ) You may be interested in integrating this patch.

My ulimit package exposes this API ([1], should finally submit it to CRAN); unfortunately this very API seems to be unsupported on OS X [2,3]. Last time I looked into it, neither of the documented settings achieved the desired effect. -Kirill [1] http://krlmlr.github.io/ulimit [2]

The previous code duplicated a lot of common code for reading and writing the cache file per data field. This change simply factors out that common code. This makes it simpler to add new tests in future. This is just refactoring, it should have no effect. --- lib/qemu.c | 375 +++++++++++++++++++++++++++++++++++++++---------------------- 1 file changed, 238 insertions(+), 137 deletions(-)

Then, please fix it to not use RLIMIT_RSS in the cygwin case. Perhaps you should just use RLIMIT_AS for cygwin. It will trigger sooner than RLIMIT_RSS but that's probably okay.
