Sky2 driver will oops referencing bad memory if used on a dual port card. The problem is accessing past end of MIB counter space. Applies for both 2.6.17 and 2.6.16 (with fuzz) Signed-off-by:

After resetting the hardware on a tx_timeout, call netif_wake_queue() only if we have free tx descriptors. Also, attempt to recover if mv643xx_eth_start_xmit() is called when there are fewer free tx descriptors than expected. The BUG_ON() call we are replacing was hit on a tx_timeout that called netif_wake_queue(), indirectly via netif_device_attach(), even though we did not have enough free tx descriptors. Signed-off-by:

Fix the tx interrupt handler to free completed tx descriptors even when NAPI is enabled. Otherwise, the tx queue would fill up resulting in poor performance and "NETDEV WATCHDOG: <iface>: transmit timed out" messages. Signed-off-by:

In vsyscall function do_vgettimeofday(), some functions are declared as inlined, which is a hint for gcc to compile the function inlined but it not forced. Sometimes compiler does not compile the function as inlined, so here inline is replaced by __always_inline prefix. It does not happen in gcc compiler actually, but it possibly happens. Signed-off-by:

When nolapic was passed or the local APIC was disabled for another reason ACPI would still parse the IO-APICs until these were explicitely disabled with noapic. Usually this resulted in a non booting configuration unless "nolapic noapic" was used. I also disabled the local APIC parsing in this case, although that's only cosmetic (suppresses a few printks) This hopefully makes nolapic work in all cases.

Since the visual STATIC_PSEUDOCOLOR has a read-only colormap, use logos with 16 colors only since these logos use the console palette. This has a higher likelihood that the logo will display correctly. Signed-of-by:

Antonino A. Daplas authored
Bugzilla Bug 6299: A pixel size of 8 bits produces wrong logo colors in x86_64. The driver has 2 methods for setting the color map, using the protected mode interface provided by the video BIOS and directly writing to the VGA registers. The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS. If both methods are unsupported, change the visual of vesafb to STATIC_PSEUDOCOLOR. Signed-off-by:

sparc32 lacks vga.h, so lots of fbdev drivers won't compile. There are no sparc32 systems with PCI slots, so it's a bit moot. The patch gives sparc32 a copy of the sparc64 vga.h. It fixes sparc32 allmodconfig without mucking up fbdev Kconfig and gives us wider compile coverage. Cc: "Antonino A. Daplas" <adaplas@pol.net> Acked-by:

It's very easy for the server to DOS itself by just giving out too many delegations. For now we just solve the problem with a dumb hard limit. Eventually we'll want a smarter policy. Signed-off-by:

We should be shutting down rpciod for the callback channel when we shut down the server. Also note that we do rpciod_up() and create the callback client *before* setting cb_set--the cb_set only determines whether the initial null was succesful. So cb_set is not a reliable determiner of whether we need to clean up, only cb_client is. Signed-off-by:

Every caller of svc_take_page ignores its return value and assumes it succeeded. So just WARN() instead of returning an ignored error. This would have saved some time debugging a recent nfsd4 problem. If there are still failure cases here, then the result is probably that we overwrite an earlier part of the reply while xdr-encoding. While the corrupted reply is a nasty bug, it would be worse to panic here and create the possibility of a remote DOS; hence WARN() instead of BUG(). Signed-off-by:

We're using svc_take_page here to get another page for the tail in case one wasn't already allocated. But there isn't always guaranteed to be another page available. Also fix a typo that made us check the tail buffer for space when we meant to be checking the head buffer. Signed-off-by:

In v4 we grab an extra page just for the padding of returned data. The formula that the rpc server uses to allocate pages for the response doesn't take into account this extra page. Instead of adjusting those formulae, we adopt the same solution as v2 and v3, and put the "tail" data in the same page as the "head" data. Signed-off-by:

Since nfsd_setuser() is already called from any operation that uses the current filehandle (because it's called from fh_verify), there's no reason to call it from putrootfh. Signed-off-by:

In addition to setting the processes filesystem id's, nfsd_setuser also modifies the value of the rq_cred which stores the id's that originally came from the rpc call, for example to reflect root squashing. There's no real reason to do that--the only case where rqstp->rq_cred is actually used later on is in the NFSv4 SETCLIENTID/SETCLIENTID_CONFIRM operations, and there the results are the opposite of what we want--those two operations don't deal with the filesystem at all, they only record the credentials used with the rpc call for later reference (so that we may require the same credentials be used on later operations), and the credentials shouldn't vary just because there was or wasn't a previous operation in the compound that referred to some export This fixes a bug which caused mounts from Solaris clients to fail.
