In DSACK case, some events are not extraordinary, such as packet duplication generated DSACK. They can arrive easily below snd_una when undo_marker is not set (TCP being in CA_Open), counting such DSACKs amoung SACK discards will likely just mislead if they occur in some scenario when there are other problems as well. Similarly, excessively delayed packets could cause "normal" DSACKs. Therefore, separate counters are allocated for DSACK events. Signed-off-by:

SACK processing code has been a sort of russian roulette as no validation of SACK blocks is previously attempted. Besides, it is not very clear what all kinds of broken SACK blocks really mean (e.g., one that has start and end sequence numbers reversed). So now close the roulette once and for all. Signed-off-by:

Only thing that tiny function does is rearming the RTO (if necessary), name it accordingly. Signed-off-by:

Get rid of using DPRINTK macro in ATM and use pr_debug (in kernel.h). Using the standard macro is cleaner and forces code to check for bad arguments and formatting. Fixes from Thomas Graf. Signed-off-by:

The ethernet header management only needs to handle a fixed size address (6 bytes). If the memcpy/memset are changed to be passed a constant length, then compiler can optimize for this case (and if it is smart eliminate string instructions). Signed-off-by:

These functions are only used once and are a lot easier to understand if inlined directly into the function. Fixes by Masahide NAKAMURA. Signed-off-by:

nlmsg_parse() puts attributes at array[type] so the indexing method can be simpilfied by removing the obscuring "- 1". Signed-off-by:
-
Thomas Graf authored
Adds a policy defining the minimal payload lengths for all the attributes allowing for most attribute validation checks to be removed from in the middle of the code path. Makes updates more consistent as many format errors are recognised earlier, before any changes have been attempted. Signed-off-by:

Thomas Graf authored
Uses nlmsg_parse() to parse the attributes. This actually changes behaviour as unknown attributes (type > MAXTYPE) no longer cause an error. Instead unknown attributes will be ignored henceforth to keep older kernels compatible with more recent userspace tools. Signed-off-by:

Moves all complex message size calculation into own inlined helper functions and makes use of the type-safe netlink interface. Using nlmsg_new() simplifies the calculation itself as it takes care of the netlink header length by itself. Signed-off-by:

The code was too complicated, if p > 0 in ccid3_hc_tx_no_feedback_timer the timestamp was being obtained to be passed to ccid3_hc_tx_update_x, where only if p > 0 the timestamp was needed, so just leave it to ccid3_hc_tx_update_x to obtain the timestamp if needed. This will help in the upcoming changesets where we'll convert t_ld to ktime_t. We'll eventually try to reuse ktime_get_real() calls again. Signed-off-by:

This patch introduces autotuning to the sctp buffer management code similar to the TCP. The buffer space can be grown if the advertised receive window still has room. This might happen if small message sizes are used, which is common in telecom environmens. New tunables are introduced that provide limits to buffer growth and memory pressure is entered if to much buffer spaces is used. Signed-off-by:

Several get/set functions can be handled by a passing the ethtool_op function pointer directly to a generic function. This permits deletion of a fair bit of redundant code. Signed-off-by:
