* mac80211/cfg80211: Add BSS configuration options for AP modeJouni Malinen2008-08-295-0/+139
| | | | | | | | | | | | This change adds a new cfg80211 command, NL80211_CMD_SET_BSS, to allow AP mode BSS parameters to be changed from user space (e.g., hostapd). The drivers using mac80211 are expected to be modified with separate changes to use the new BSS info parameter for short slot time in the bss_info_changed() handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't access the cache entry outside of our critical read-locked region, because someone may free that entry. Also getting an entry under read lock, then locking for write and trying to delete that entry looks fishy, but should be no problem here, because we're only comparing a pointer. Also there is no need for our own rwlock, there is already one in the service structure for use in the schedulers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't access the cache entry outside of our critical read-locked region, because someone may free that entry. And we also need to check in the critical region wether the destination is still available, i.e. it's not in the trash. If we drop our reference counter, the destination can be purged from the trash at any time. Our caller only guarantees that no destination is moved to the trash, while we are scheduling. Also there is no need for our own rwlock, there is already one in the service structure for use in the schedulers.

This is useful since there are various module inter-dependencies. The debug flag can now be toggled at runtime using echo 1 > /sys/module/dccp/parameters/dccp_debug echo 1 > /sys/module/dccp_ccid2/parameters/ccid2_debug echo 1 > /sys/module/dccp_ccid3/parameters/ccid3_debug echo 1 > /sys/module/dccp_tfrc_lib/parameters/tfrc_debug The last is not very useful yet, since no code at the moment calls the tfrc_debug() macro.

In case (1) the write queue is empty. This patch empties the write queue, if in case (2) or (3) it was not yet empty. This avoids triggering the write-queue BUG_TRAP in sk_stream_kill_queues() later on. It also seems natural to do: when breaking an association, to delete all packets that were originally intended for the soon-disconnected end (compare with call to tcp_write_queue_purge in tcp_disconnect()).

Hence in the following cases erratic options will be ignored: 1. The type byte of a multi-byte option is the last byte of the header options (i.e. effective option length of 1). 2. The value of the length byte is less than the minimum 2. This has been changed from previously 3: although no multi-byte option with a length less than 3 yet exists (cf. table 3 in 5.8), a length of 2 is valid. (The switch-statement in dccp_parse has further per-option length checks.) 3. The option length exceeds the length of the remaining option space. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>

In the LISTEN and RESPOND states, the endpoint correctly reponds with Reset, while in the REQUEST/OPEN states, packets with option errors are just ignored. The packet sequence is as follows: Case 1: Endpoint A Endpoint B (CLOSED) (CLOSED) <---------------- REQUEST RESPONSE -----------------> (*1) (with invalid option) <---------------- RESET (with Reset Code 5, "Option Error") (*1) currently just ignored, no Reset is sent Case 2: Endpoint A Endpoint B (OPEN) (OPEN) DATA-ACK -----------------> (*2) (with invalid option) <---------------- RESET (with Reset Code 5, "Option Error") (*2) currently just ignored, no Reset is sent This patch fixes the problem, by generating a Reset instead of silently ignoring option errors.
