2005-10-12[BRIDGE]: fix race on bridge del ifStephen Hemminger
This fixes the RCU race on bridge delete interface. Basically, the network device has to be detached from the bridge in the first step (pre-RCU), rather than later. At that point, no more bridge traffic will come in, and the other code will not think that network device is part of a bridge. This should also fix the XEN test problems.

2005-10-12[SPARC64]: Fix boot failures on SunBlade-150David S. Miller
The sequence to move over to the Linux trap tables from the firmware ones needs to be more air tight. It turns out that to be %100 safe we do need to be able to translate OBP mappings in our TLB miss handlers early. In order not to eat up a lot of kernel image memory with static page tables, just use the translations array in the OBP TLB miss handlers. That solves the bulk of the problem. Furthermore, to make sure the OBP TLB miss path will work even before the fixed MMU globals are loaded, explicitly load %g1 to TLB_SFSR at the beginning of the i-TLB and d-TLB miss handlers. To ease the OBP TLB miss walking of the prom_trans[] array, we sort it then delete all of the non-OBP entries in there (for example, there are entries for the kernel image itself which we're not interested in at all). We also save about 32K of kernel image size with this change. Not a bad side effect :-) There are still some reasons why trampoline.S can't use the setup_trap_table() yet. The most noteworthy are: 1) OBP boots secondary processors with non-bias'd stack for some reason. This is easily fixed by using a small bootup stack in the kernel image explicitly for this purpose. 2) Doing a firmware call via the normal C call prom_set_trap_table() goes through the whole OBP enter/exit sequence that saves and restores OBP and Linux kernel state in the MMUs. This path unfortunately does a "flush %g6" while loading up the OBP locked TLB entries for the firmware call. If we setup the %g6 in the trampoline.S code properly, that is in the PAGE_OFFSET linear mapping, but we're not on the kernel trap table yet so those addresses won't translate properly. One idea is to do a by-hand firmware call like we do in the early bootup code and elsewhere here in trampoline.S But this fails as well, as aparently the secondary processors are not booted with OBP's special locked TLB entries loaded. These are necessary for the firwmare to processes TLB misses correctly up until the point where we take over the trap table. This does need to be resolved at some point. Signed-off-by: David S.

2005-10-12[PATCH] ppc32: Tell userland about lack of standard TBBenjamin Herrenschmidt
Glibc is about to get some new high precision timer stuff that relies on the standard timebase of the PPC architecture. However, some (rare & old) CPUs do not have such timebase and it is a bit annoying to have your stuff just crash because you are running on the wrong CPU... This exposes to userland a CPU feature bit that tells that the current processor doesn't have a standard timebase. It's negative logic so that glibc will still "just work" on older kernels (it will just be unhappy on those old CPUs but that doesn't really matter as distro tend to update glibc & kernel at the same time).

2005-10-12[PATCH] ppc32: Fix timekeepingBenjamin Herrenschmidt
Interestingly enough, ppc32 had broken timekeeping for ages... It worked, but probably drifted a bit more than could be explained by the actual bad precision of the timebase calibration. We discovered that recently when somebody figured out that the common code was using CLOCK_TICK_RATE to correct the timekeeing, and ppc32 had a completely bogus value for it. This patch turns it into something saner. Probably not as good as doing something based on the actual timebase frequency precision but I'll leave that sort of math to others. This at least makes it better for the common HZ values. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-11[PATCH] ppc highmem fixPaolo Galtieri
I've noticed that the calculations for seg_size and nr_segs in __dma_sync_page_highmem() (arch/ppc/kernel/dma-mapping.c) are wrong. The incorrect calculations can result in either an oops or a panic when running fsck depending on the size of the partition. The problem with the seg_size calculation is that it can result in a negative number if size is offset > size. The problem with the nr_segs caculation is returns the wrong number of segments, e.g. it returns 1 when size is 200 and offset is 4095, when it should return 2 or more.

2005-10-11[PATCH] nfsacl: Solaris VxFS compatibility fixAndreas Gruenbacher
Here is a compatibility fix between Linux and Solaris when used with VxFS filesystems: Solaris usually accepts acl entries in any order, but with VxFS it replies with NFSERR_INVAL when it sees a four-entry acl that is not in canonical form. It may also fail with other non-canonical acls -- I can't tell, because that case never triggers: We only send non-canonical acls when we fake up an ACL_MASK entry. Instead of adding fake ACL_MASK entries at the end, inserting them in the correct position makes Solaris+VxFS happy. The Linux client and server sides don't care about entry order. The three-entry-acl special case in which we need a fake ACL_MASK entry was handled in xdr_nfsace_encode. The patch moves this into nfsacl_encode.

2005-10-11[PATCH] dell_rbu: changes in packet update mechanismAbhay Salunke
In the current dell_rbu code ver 2.0 the packet update mechanism makes the user app dump every individual packet in to the driver. This adds in efficiency as every packet update makes the /sys/class/firmware/dell_rbu/loading and data files to disappear and reappear again. Thus the user app needs to wait for the files to reappear to dump another packet. This slows down the packet update tremendously in case of large number of packets. I am submitting a new patch for dell_rbu which will change the way we do packet updates; In the new method the user app will create a new single file which has already packetized the rbu image and all the packets are now staged in this file. This driver also creates a new entry in /sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet size here before downloading the packet file. The user should do the following: create one single file which has all the packets stacked together. echo the packet size in to /sys/devices/platform/dell_rbu/packet_size. echo 1 > /sys/class/firmware/dell_rbu/loading cat the packetfile > /sys/class/firmware/dell_rbu/data echo 0 > /sys/class/firmware/dell_rbu/loading The driver takes the file which came through /sys/class/firmware/dell_rbu/data and takes chunks of paket_size data from it and place in contiguous memory. This makes packet update process very efficient and fast. As all the packet update happens in one single operation. The user can still read back the downloaded file from /sys/devices/platform/dell_rbu/data.

2005-10-10[IPSEC] Fix block size/MTU bugs in ESPHerbert Xu
This patch fixes the following bugs in ESP: * Fix transport mode MTU overestimate. This means that the inner MTU is smaller than it needs be. Worse yet, given an input MTU which is a multiple of 4 it will always produce an estimate which is not a multiple of 4. For example, given a standard ESP/3DES/MD5 transform and an MTU of 1500, the resulting MTU for transport mode is 1462 when it should be 1464. The reason for this is because IP header lengths are always a multiple of 4 for IPv4 and 8 for IPv6. * Ensure that the block size is at least 4. This is required by RFC2406 and corresponds to what the esp_output function does. At the moment this only affects crypto_null as its block size is 1.
