2017-07-18atm: zatm: Fix an error handling path in 'zatm_init_one()'Christophe Jaillet1-1/+1
If 'dma_set_mask_and_coherent()' fails, we must undo the previous 'pci_request_regions()' call. Adjust corresponding 'goto' to jump at the right place of the error handling path. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S. Miller <davem@davemloft.net>

2017-06-16networking: make skb_push & __skb_push return void pointersJohannes Berg1-1/+1
It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) @@ expression SKB, LEN; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; @@ - fn(SKB, LEN)[0] + *(u8 *)fn(SKB, LEN) Note that the last part there converts from push(...)[0] to the more idiomatic *(u8 *)push(...).

2017-06-16networking: make skb_put & friends return void pointersJohannes Berg2-8/+8
It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c.

A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this. An spatch similar to the one for skb_put_zero() converts many of the places using it: @@ identifier p, p2; expression len, skb, data; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_data(skb, data, len); | -p = (t)skb_put(skb, len); +p = skb_put_data(skb, data, len); ) ( p2 = (t2)p; -memcpy(p2, data, len); | -memcpy(p, data, len); ) @@ type t, t2; identifier p, p2; expression skb, data; @@ t *p; ...

Pull IDR rewrite from Matthew Wilcox: "The most significant part of the following is the patch to rewrite the IDR & IDA to be clients of the radix tree. But there's much more, including an enhancement of the IDA to be significantly more space efficient, an IDR & IDA test suite, some improvements to the IDR API (and driver changes to take advantage of those improvements), several improvements to the radix tree test suite and RCU annotations. The IDR & IDA rewrite had a good spin in linux-next and Andrew's tree for most of the last cycle. Coupled with the IDR test suite, I feel pretty confident that any remaining bugs are quite hard to hit. 0-day did a great job of watching my git tree and pointing out problems; as it hit them, I added new test-cases to be sure not to be caught the same way twice" Willy goes on to expand a bit on the IDR rewrite rationale: "The radix tree and the IDR use very similar data structures. Merging the two codebases lets us share the memory allocation pools, and results in a net deletion of 500 lines of code. It also opens up the possibility of exposing more of the features of the radix tree to users of the IDR (and I have some interesting patches along those lines waiting for 4.12) It also shrinks the size of the 'struct idr' from 40 bytes to 24 which will shrink a fair few data structures that embed an IDR" * 'idr-4.11' of git://git.infradead.org/users/willy/linux-dax: (32 commits) radix tree test suite: Add config option for map shift idr: Add missing __rcu annotations radix-tree: Fix __rcu annotations radix-tree: Add rcu_dereference and rcu_assign_pointer calls radix tree test suite: Run iteration tests for longer radix tree test suite: Fix split/join memory leaks radix tree test suite: Fix leaks in regression2.c radix tree test suite: Fix leaky tests radix tree test suite: Enable address sanitizer radix_tree_iter_resume: Fix out of bounds error radix-tree: Store a pointer to the root in each node radix-tree: Chain preallocated nodes through ->parent radix tree test suite: Dial down verbosity with -v radix tree test suite: Introduce kmalloc_verbose idr: Return the deleted entry from idr_remove radix tree test suite: Build separate binaries for some tests ida: Use exceptional entries for small IDAs ida: Move ida_bitmap to a percpu variable Reimplement IDR and IDA using the radix tree radix-tree: Add radix_tree_iter_delete ...
2017-02-27lib/vsprintf.c: remove %Z supportAlexey Dobriyan5-31/+17
Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

2016-08-18atm: fore200e: Do not drop const qualifierLABBE Corentin1-3/+3
The data member of structure firmware is const and this constness is dropped by some cast. This patch add some const for keeping the const information. Signed-off-by: LABBE Corentin <clabbe.montjoie@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-07-19drivers: atm: nicstar: Use the correct function to free some resourcesChristophe Jaillet1-1/+2
In 'get_scq', 'dma_alloc_coherent' has been used to allocate some resources, so we need to free them using 'dma_free_coherent' instead of 'kfree'. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S. Miller <davem@davemloft.net>

Convert a call to init_timer and accompanying intializations of the timer's data and function fields to a call to setup_timer. The Coccinelle semantic patch that fixes this problem is as follows: @@ expression t,d,f,e1; identifier x1; statement S1; @@ ( -t.data = d; | -t.function = f; | -init_timer(&t); +setup_timer(&t,f,d); | -init_timer_on_stack(&t); +setup_timer_on_stack(&t,f,d); ) <... when != S1 t.x1 = e1; ...> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: David S.

2016-05-31atm: iphase: off by one in rx_pkt()Dan Carpenter1-1/+1
The iadev->rx_open[] array holds "iadev->num_vc" pointers (this code assumes that pointers are 32 bits). So the > here should be >= or else we could end up reading a garbage pointer from one element beyond the end of the array.

2016-05-31atm: firestream: add more reserved stringsDan Carpenter1-1/+5
This bug was there when the driver was first added in back in year 2000. It causes a Smatch warning: drivers/atm/firestream.c:849 process_incoming() error: buffer overflow 'res_strings' 60 <= 63 There are supposed to be 64 entries in this array and the missing strings are clearly in the 30 40 range. I added them as reserved 37 to reserved 40. It's possible that strings are really supposed to be added in the middle instead of at the end, but this approach is safe, in that it fixes the bug and doesn't break anything that wasn't already broken.
