Kernel vanilla 2.6.30-RC7

Sunday, 24 May 2009 08:22

altÈ disponibile un nuovo kernel 2.6.30-rc7 settimo rilascio da http://www.kernel.org/

 

 

 

 

 

Ricordo che questo kernel è usabile con attenzione ma che manca di tutte le patch e moduli 3rdparty tipiche dei kernel Mandriva non essendo quello ufficiale di Mandriva.

[CIFS] Avoid open on possible directories since Samba now rejects them

commit 8db14ca12569fe885694bd3d5ff84c2d973d3cb0

[CIFS] Avoid open on possible directories since Samba now rejects them

Small change (mostly formatting) to limit lookup based open calls to
file create only.

After discussion yesteday on samba-technical about the posix lookup
regression, and looking at a problem with cifs posix open to one
particular Samba version, Jeff and JRA realized that Samba server's
behavior changed in this area (posix open behavior on files vs.
directories). To make this behavior consistent, JRA just made a
fix to Samba server to alter how it handles open of directories (now
returning the equivalent of EISDIR instead of success). Since we don't
know at lookup time whether the inode is a directory or file (and
thus whether posix open will succeed with most current Samba server),
this change avoids the posix open code on lookup open (just issues
posix open on creates). This gets the semantic benefits we want
(atomicity, posix byte range locks, improved write semantics on newly
created files) and file create still is fast, and we avoid the problem
that Jeff noticed yesterday with "openat" (and some open directory
calls) of non-cached directories to one version of Samba server, and
will work with future Samba versions (which include the fix jra just
pushed into Samba server). I confirmed this approach with jra
yesterday and with Shirish today.

Posix open is only called (at lookup time) for file create now.
For opens (rather than creates), because we do not know if it
is a file or directory yet, and current Samba no longer allows
us to do posix open on dirs, we could end up wasting an open call
on what turns out to be a dir. For file opens, we wait to call posix
open till cifs_open. It could be added here (lookup) in the future
but the performance tradeoff of the extra network request when EISDIR
or EACCES is returned would have to be weighed against the 50%
reduction in network traffic in the other paths.

icom: fix rmmod crash

Actually the icom driver is crashing when is being removed because
the driver is kfreeing the adapter structure before calling
pci_release_regions(), which result in the following error:

Unable to handle kernel paging request for data at address 0x6b6b6b6b6b6b6d33
Faulting instruction address: 0xc000000000246b80

Potete scaricarlo da qui,, al solito tasto destro salva destinazione con nome.

Ecco il log dei fix.

ciao.

grissino.
