Subject: negative seek offsets in VFS
Date: 25 May 2005 18:39:05 +0200
Date: Wed, 25 May 2005 18:39:05 +0200 [thread overview]
Message-ID: <20050525163905.GP86087@muc.de> (raw)
My x86-64 users are complaining again that they cannot reach kernel
text addresses in /dev/kmem. The reason is that they are negative and
the the VFS read and seek code just EINVALs them. For seek I could
fix it in drivers/char/mem.c, but for read/pread/write etc.
it needs VFS changes.
I dont quite get why they are there anyways, the super block has
max file size field and checking against that should be enough for
all the filesystems, no?
Opinions?
