The call to strsep, however, modifies clone, so a pointer to the front of the string is kept in saved_clone, to make it possible to free it.

| * tcp: fix three tcp sysctls tuningEric Dumazet2010-08-251-17/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discovered by Anton Blanchard, current code to autotune tcp_death_row.sysctl_max_tw_buckets, sysctl_tcp_max_orphans and sysctl_max_syn_backlog makes little sense. The bigger a page is, the less tcp_max_orphans is : 4096 on a 512GB machine in Anton's case. (tcp_hashinfo.bhash_size * sizeof(struct inet_bind_hashbucket)) is much bigger if spinlock debugging is on. Its wrong to select bigger limits in this case (where kernel structures are also bigger) bhash_size max is 65536, and we get this value even for small machines. A better ground is to use size of ehash table, this also makes code shorter and more obvious. Based on a patch from Anton, and another from David.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Anton Blanchard when we use percpu_counter_read_positive() to make our orphan socket limit checks, the check can be off by up to num_cpus_online() * batch (which is 32 by default) which on a 128 cpu machine can be as large as the default orphan limit itself.

Eric attempted to fix it, but the fix created even worse problems. However, the original motivation I had when I added the code that turned out to be racy is no longer clear to me, since we only copy up to skb->len to userspace, which doesn't include the frag_list length. As a result, not doing any frag_list clearing and restoring avoids the race condition, while not introducing any other problems. Additionally, while preparing this patch I found that since none of the remaining netlink code is really aware of the frag_list, we need to use the original skb's information for packet information and credentials. This fixes, for example, the group information received by compat tasks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a limit for nframes as the number of frames in TX_SETUP and RX_SETUP are derived from a single byte multiplex value by default. Use-cases that would require to send/filter more than 256 CAN frames should be implemented in userspace for complexity reasons anyway. Additionally the assignments of unsigned values from userspace to signed values in kernelspace and vice versa are fixed by using unsigned values in kernelspace consistently.

| | | * | Bluetooth: Fix incorrect setting of remote_tx_win for L2CAP ERTMMat Martineau2010-08-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | remote_tx_win is intended to be set on receipt of an L2CAP configuration request. The value is used to determine the size of the transmit window on the remote side of an ERTM connection, so L2CAP can stop sending frames when that remote window is full. An incorrect remote_tx_win value will cause the stack to not fully utilize the tx window (performance impact), or to overfill the remote tx window (causing dropped frames or a disconnect). This patch removes an extra setting of remote_tx_win when a configuration response is received. The transmit window has a different meaning in a response - it is an informational value less than or equal to the local tx_win.

This fixes a bug where a little-endian MPS value is compared to a native CPU value. On big-endian processors, this can cause ERTM and streaming mode segmentation to produce PDUs that are larger than the remote stack is expecting, or that would produce fragmented skbs that the current FCS code cannot handle.

Userspace passes the desired error number as an option in the payload: "#dnserror=<number>" Userspace must map h_errno from the name resolution routines to an appropriate Linux error before passing it up. Something like the following mapping is recommended: [HOST_NOT_FOUND] = ENODATA, [TRY_AGAIN] = EAGAIN, [NO_RECOVERY] = ECONNREFUSED, [NO_DATA] = ENODATA, in lieu of Linux errors specifically for representing name service errors. The filesystem must map these errors appropropriately before passing them to userspace. AFS is made to map ENODATA and EAGAIN to EDESTADDRREQ for the return to userspace; ECONNREFUSED is allowed to stand as is. The error can be seen in /proc/keys as a negative number after the description of the key. Compare, for example, the following key entries: 2f97238c I--Q-- 1 53s 3f010000 0 0 dns_resol afsdb:grand.centrall.org: -61 338bfbbe I--Q-- 1 59m 3f010000 0 0 dns_resol afsdb:grand.central.org: 37 If the error option is supplied in the payload, the main part of the payload is discarded. The key should have an expiry time set by userspace.

The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb.
