* lib/llist.c: remove redundant includeRasmus Villemoes2015-02-121-1/+0
| | | | | | | | | | This file doesn't seem to use anything provided by linux/interrupt.h or anything recursively included through that. Removing it produces byte-identical output, while reducing .llist.o.cmd from 541 to 156 lines.

* lib/list_sort.c: rearrange includesRasmus Villemoes2015-02-121-2/+5
| | | | | | | | | | | | | | | | | | | | | | | Memory allocation only happens in the self test, just as random numbers are only used there. So move the inclusion of slab.h inside the CONFIG_TEST_LIST_SORT. We don't need module.h and all of the stuff it carries with it, so replace with export.h and compiler.h. Unfortunately, the ARRAY_SIZE macro from kernel.h requires the user to ensure bug.h is also included (for BUILD_BUG_ON_ZERO, used by __must_be_array). We used to get that through some maze of nested includes, but just include it explicitly. linux/string.h is then only included implicitly through kernel.h->printk.h->dynamic_debug.h, but only if !CONFIG_DYNAMIC_DEBUG, so just include it explicitly (for memset). objdump -d says the generated code is the same, and wc -l says that lib/.list_sort.o.cmd went from 579 to 165 lines.

* lib/halfmd4.c: simplify includesRasmus Villemoes2015-02-121-1/+1
| | | | | | | | | | | | | We only need EXPORT_SYMBOL, so compiler.h and export.h suffice. This means linux/types.h is no longer implicitly included, so add an include of uapi/linux/types.h to linux/cryptohash.h for __u32. Other users of cryptohash.h cannot be affected, since they must already have been including uapi/linux/types.h in order for gcc not to complain about unknown types.

| | | | | | | | | | | | sort.c doesn't use facilities from kernel.h, but does use some types defined in linux/types.h. Include the latter directly instead of relying on some other header doing it. Similarly, include linux/export.h directly instead of through module.h. This removes 80 lines from the dependency file .sort.o.cmd.

* hexdump: make it return number of bytes placed in bufferAndy Shevchenko2015-02-122-18/+100
| | | | | | | | | | | | | | This patch makes hexdump return the number of bytes placed in the buffer excluding trailing NUL. In the case of overflow it returns the desired amount of bytes to produce the entire dump. Thus, it mimics snprintf(). This will be useful for users that would like to repeat with a bigger buffer.

* hexdump: fix ascii column for the tail of a dumpAndy Shevchenko2015-02-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | In the current implementation we have a floating ascii column in the tail of the dump. For example, for row size equal to 16 the ascii column as in following table group size \ length 8 12 16 1 50 50 50 2 22 32 42 4 20 29 38 8 19 - 36 This patch makes it the same independently of amount of bytes dumped. The change is safe since all current users, which use ASCII part of the dump, rely on the group size equal to 1. The patch doesn't change behaviour for such group size (see the table above).

Also, simplify the implementation and as a side effect make the result fully defined, returning nbits for ord >= weight, in analogy with what find_{first,next}_bit does.

* lib/bitmap.c: simplify bitmap_pos_to_ordRasmus Villemoes2015-02-121-16/+6
| | | | | | | | | | | | | | | | | | The ordinal of a set bit is simply the number of set bits before it; counting those doesn't need to be done one bit at a time. While at it, update the parameters to unsigned int. It is not completely unthinkable that gcc would see pos as compile-time constant 0 in one of the uses of bitmap_pos_to_ord. Since the static inline frontend bitmap_weight doesn't handle nbits==0 correctly (it would behave exactly as if nbits==BITS_PER_LONG), use __bitmap_weight. Alternatively, the last line could be spelled bitmap_weight(buf, pos+1)-1, but this is simpler.

| | | | | | | | | | | | The remainder from do_div is always a u32, and after size has been reduced to be below 1000 (or 1024), it certainly fits in u32. So both remainder and sf_cap can be made u32s, the format specifiers can be simplified (%lld wasn't the right thing to use for _unsigned_ long long anyway), and we can replace a do_div with an ordinary 32/32 bit division.

* lib/string_helpers.c:string_get_size(): remove redundant prefixesRasmus Villemoes2015-02-121-4/+3
| | | | | | | | | | | | | | | | | While commit 3c9f3681d0b4 ("[SCSI] lib: add generic helper to print sizes rounded to the correct SI range") says that Z and Y are included in preparation for 128 bit computers, they just waste .text currently. If and when we get u128, string_get_size needs updating anyway (and ISO needs to come up with four more prefixes). Also there's no need to include and test for the NULL sentinel; once we reach "E" size is at most 18. [The test is also wrong; it should be units_str[units][i+1]; if we've reached NULL we're already doomed.] Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

From Alexander Duyck. 3) Remove sock_iocb altogether, from CHristoph Hellwig. 4) Allow congestion control algorithm selection via routing metrics. From Daniel Borkmann. 5) Make ipv4 uncached route list per-cpu, from Eric Dumazet. 6) Handle rfs hash collisions more gracefully, also from Eric Dumazet. 7) Add xmit_more support to r8169, e1000, and e1000e drivers. From Florian Westphal. 8) Transparent Ethernet Bridging support for GRO, from Jesse Gross. 9) Add BPF packet actions to packet scheduler, from Jiri Pirko. 10) Add support for uniqu flow IDs to openvswitch, from Joe Stringer. 11) New NetCP ethernet driver, from Muralidharan Karicheri and Wingman Kwok. 12) More sanely handle out-of-window dupacks, which can result in serious ACK storms. From Neal Cardwell. 13) Various rhashtable bug fixes and enhancements, from Herbert Xu, Patrick McHardy, and Thomas Graf. 14) Support xmit_more in be2net, from Sathya Perla. 15) Group Policy extensions for vxlan, from Thomas Graf. 16) Remove Checksum Offload support for vxlan, from Tom Herbert. 17) Like ipv4, support lockless transmit over ipv6 UDP sockets.

Instead in order to not leave stale references behind we need to: 1. When growing and searching from the new table: Search remaining chain for entry with same hash to avoid having the new table directly point to a entry with a different hash. 2. When shrinking and searching from the old table: Check if the element after the removed would create a cross reference and avoid it if so. These bugs were present from the beginning in nft_hash. Also, both insert functions calculated the hash based on the mask of the new table. This worked while growing. Wwhile shrinking, the mask of the inew table is smaller than the mask of the old table. This lead to a bit not being taken into account when selecting the bucket lock and thus caused the wrong bucket to be locked eventually.

Removal of an element may result the bucket in the larger table to point to entries which all hash to a different value than the bucket index. Thus causing two buckets to point to the same sub chain after unzipping. This is not illegal *during* the resize phase but after it has completed. Keep the old table around until all of the unzipping is done to allow the removal code to only search for matching hashed entries during this special period.

This requires multiple levels of complicated nested locking because when resizing, a single bucket of the smaller table will map to two buckets in the larger table. So far rhashtable has explicitly locked both buckets in the larger table. By excluding the highest bit of the hash from the bucket lock map and thus only allowing locks to buckets in a ratio of 1:2, the locking can be simplified a lot without losing the benefits of multiple locks. Larger tables which benefit from multiple locks will not have a single lock per bucket anyway. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
