From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.2) Gecko/20040803 Description of problem: The version this bug is being filed on is a total lie. I based this patch on 4.5.11 from sf and haven't looked in fc packages for aio support. Anyway, I wanted to see what were in the aio syscalls. So instead of seeing > $ strace ../test-aio 2>&1 | grep '^io_' > io_setup(0x1, 0x7fbffff478) = 0 > io_submit(0x2a95557000, 0x2, 0x7fbffff3e0) = 2 > io_cancel(0x2a95557000, 0x7fbffff430, 0x7fbffff380) = -1 EAGAIN (Resource temporarily unavailable) > io_getevents(0x2a95557000, 0x1, 0x2, 0x7fbffff3a0, 0x7fbffff370) = 2 > io_destroy(0x2a95557000) = 0 I wanted > $ ./strace ../test-aio 2>&1 | grep '^io_' > io_setup(1, {182894030848}) = 0 > io_submit(182894030848, 2, {{0x123, 0, 0, 0, 0}, {0x456, 0, 0, 0, 0}}) = 2 > io_cancel(182894030848, {0x123, 0, 0, 0, 0}, {...}) = -1 EAGAIN (Resource temporarily unavailable) > io_getevents(182894030848, 1, 2, {{0x123, 0x7fbffff430, -22, 0}, {0x456, 0x7fbffff3f0, -22, 0}}, {123, 456}) = 2 > io_destroy(182894030848) = 0 so I whipped up a patch that adds support. It might be fragile and bad as this is my first time diving into strace. So I'm hoping that I can get feedback and if it's suitable that it can make its way upstream and into distros. > $ gendiff . .decode-aio | diffstat > config.h.in | 3 > configure.ac | 2 > desc.c | 160 +++++++++++++++++++++++++++++++++++++++++++++ > linux/alpha/syscallent.h | 10 +- > linux/hppa/syscallent.h | 10 +- > linux/ia64/syscallent.h | 10 +- > linux/mips/syscallent.h | 10 +- > linux/powerpc/syscallent.h | 10 +- > linux/s390/syscallent.h | 10 +- > linux/s390x/syscallent.h | 10 +- > linux/syscall.h | 1 > linux/x86_64/syscallent.h | 10 +- > 12 files changed, 205 insertions(+), 41 deletions(-) I'll attach the patch once the bug is filed. DEAR BUGZILLA, IT SURE WOULD BE COOL IF I COULD ATTACH A FILE AT BUG CREATION TIME. YOURS, HOOP-JUMPER. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: run strace on an app with aio syscalls, you crap. Additional info:
Created attachment 113260 [details] decode aio syscall args; against 4.5.11
I put the patch in upstream.
