https://bugzilla.novell.com/show_bug.cgi?id=255763#c4 Jeff Mahoney changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jeffm@novell.com Status|ASSIGNED |NEEDINFO Info Provider| |schwab@novell.com --- Comment #4 from Jeff Mahoney 2007-10-23 15:11:02 MST --- The change was introduced here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdif... . it looks clean enough, but what ends up happening is that FMODE_READ check is applied to the write end of the pipe, which causes the -EACCES. Andreas, you seem to always have these sorts of specs memorized. Is returning -ENODEV a requirement here or just LTP (yet again) codifying observed behavior rather than enforcing the spec? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=255763#c5 --- Comment #5 from Jeff Mahoney 2007-10-23 15:12:33 MST --- Created an attachment (id=180117) --> (https://bugzilla.novell.com/attachment.cgi?id=180117) [PATCH] mmap: restore -ENODEV on missing f_op->mmap Commit 80c5606c3b45e0176c32d3108ade1e1cb0b954f3 from Linus moved the VM_MAYEXEC code further down, but in the process broke the mmap_23_1 test from the LTP suite. Moving it further means that the test for FMODE_READ ends up above the test for f_op->mmap. If the write side of the pipe is called for mmap(), we end up returning -EACCES rather than -ENODEV (is this required?) I'll submit this upstream if it turns out to be required by the spec. Otherwise, I'm closing as WONTFIX. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This test is trying to mmap PROT_READ on the write side of the pipe. Both error codes are valid. Either way, it's a change in behavior. I've submitted the patch upstream, and I'll close this bug according to the result of the submission. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've checked in a patch to STABLE and submitted it to ltp so it passes the test. It's looking for PROT_READ on the write end of the pipe, so this will allow it to pass the permission test and fail the op->mmap test. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
