2014-10-27ipw2x00: remove unused ->ibss_dfs pointerDan Carpenter1-14/+1
The ->ibss_dfs pointer is always allocated with a user controlled length. This caused a static checker warning because what if the length was zero? In that case, any dereference of ->ibss_dfs would lead to an Oops. It turns out that this isn't a problem because the ->ibss_dfs pointer is never used. This patch deletes it along with all the related code. In particular the entire libipw_network_reset() function can be removed.

2010-11-06ipw2x00: remove the right /proc/net entryLinus Torvalds1-4/+5
Commit 27ae60f8f7aa ("ipw2x00: replace "ieee80211" with "libipw" where appropriate") changed DRV_NAME to be "libipw", but didn't properly fix up the places where it was used to specify the name for the /proc/net/ directory. For backwards compatibility reasons, that directory name remained "ieee80211", but due to the DRV_NAME change, the error case printouts and the cleanup functions now used "libipw" instead. Which made it all fail badly. For example, on module unload as reported by Randy: WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e() name 'libipw' because it's trying to unregister a /proc directory that obviously doesn't even exist. Clean it all up to use DRV_PROCNAME for the actual /proc directory name. Reported-and-tested-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Pavel Roskin <proski@gnu.org> Cc: John W.

2010-03-15ipw2x00: replace "ieee80211" with "libipw" where appropriatePavel Roskin1-7/+6
"ieee80211" was the old name of the common library for ipw2100 and ipw2200. It was renamed to "libipw", but some occurrences of the old name remained. Rename alloc_ieee80211() to alloc_libipw() and free_ieee80211() to free_libipw(). Adjust comments and label names. Change prefixes in diagnostic messages. Keep /proc/net/ieee80211 under the original name to avoid breaking user interface. Move the affected EXPORT_SYMBOL macros to their proper places.

2010-03-11libipw: split ieee->networks into small piecesZhu Yi1-20/+17
The ieee->networks consists of 128 struct libipw_network entries. If we allocate this chunk of memory altogether, it ends up with an order 4 page allocation. High order page allocation is likely to fail on system high load. This patch splits the big chunk memory allocation into small pieces, each is 344 bytes, allocates them with 128 times.

2009-11-24libipw: initiate cfg80211 API conversion (v2)John W. Linville1-3/+35
Initiate the conversion of libipw to the new cfg80211 configuration API. For now, leave CONFIG_IPW2200_PROMISCUOUS stuff alone. Eventually migrate it to cfg80211 when the add/del/change_virtual_intf methods are implemented. (v2: Fix unconditional wiphy_unregister in libipw which was causing problems for ipw2100, somewhat based on prior attempted fix by Zhu Yi <yi.zhu@intel.com>. Previously both original version of this patch and Zhu Yi's fix attempt were reverted due to discovery of regressions. -- JWL) Signed-off-by: John W. Linville <linville@tuxdriver.com>

This reverts commit b8ecd988b1670035a05035c553c08331214d6603. Due to poor API call balancing by me, this commit not only broke ipw2200 if it can't find it's firmware, it broke ipw2100 basically anytime you removed the module. At this point in the cycle, let's just put it back to a sane state and try again next time... Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-10-30ipw2200: fix oops on missing firmwareZhu Yi1-5/+9
For non-monitor interfaces, the syntax for alloc_ieee80211/free_80211 is wrong. Because alloc_ieee80211 only creates (wiphy_new) a wiphy, but free_80211() does wiphy_unregister() also. This is only correct when the later wiphy_register() is called successfully, which apparently is not the case for your fw doesn't exist one.
