The patch titled Subject: drivers/hid/uhid.c: check write() bitness using in_compat_syscall has been added to the -mm tree. Its filename is uhid-check-write-bitness-using-in_compat_syscall.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/uhid-check-write-bitness-using-in_compat_syscall.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/uhid-check-write-bitness-using-in_compat_syscall.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Andy Lutomirski <luto@xxxxxxxxxx> Subject: drivers/hid/uhid.c: check write() bitness using in_compat_syscall uhid changes the format expected in write() depending on bitness. It should check the syscall bitness directly.
