2009-10-27libertas: Check return status of command functionsAmitkumar Karwar
Return status of lbs_prepare_and_send_command and lbs_cmd_with_response functions is not checked at some places. Those checks are added.

2009-08-28libertas: add NULL check on return value of get_zeroed_pageKiran Divekar

2008-10-28net: convert print_mac to %pMJohannes Berg
This converts pretty much everything to print_mac. There were a few things that had conflicts which I have just dropped for now, no harm done. I've built an allyesconfig with this and looked at the files that weren't built very carefully, but it's a huge patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S.

2008-04-16libertas: convert libertas driver to use an event/cmdresp queueHolger Schurig
This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo object for events and a swapping buffer scheme for the command response to preserve the zero-copy semantics of the CF driver and keep memory usage low. The main thread should only ever touch the buffer indexed by priv->resp_idx, while the interface code is free to write to the second buffer, then swap priv->resp_idx under the driver spinlock. The firmware specs only permit one in-flight command, so there will only ever be one command response to process at a time.

2008-03-25libertas: store rssi as an u32Holger Schurig
Don't store an (hardware base) u8 value in bss_descriptor, but just an unsigned int (RSSI is really unsigned). Compilers generate more efficent code for ints than for bytes.

2008-03-25libertas: remove lots of unused stuffHolger Schurig
This removes many unused function parameters as well as some not-implemented functions, e.g. CMD_802_11_GET_STATS. The silly lbs_set_cmd_ctrl_node() function is now also gone.

2008-03-13libertas: implement SSID scanning for SIOCSIWSCANHolger Schurig
After my bit scan re-writing the SIOCSIWSCAN wext ioctl no longer supported scanning for a specific SSID. However, wpa_supplicant is a possible user of this ioctl, so here is code that add's this. While passing, removed even more of the debugfs-based scanning. You can (and should) the SIOCSIWSCAN to ask for scans, so there is no need for proprietary interfaces for scanning. And, besides, the scan result couldn't be used further, e.g. not for associating.

2008-02-29libertas: rename/document scan_channelHolger Schurig
Rename last_scanned_channel to scan_channel, just so that a grep for struct bss_descriptor's last_scanned element doesn't show up so many positives.

2008-01-28libertas: stop debugfs code looking at cmdpendingqDavid Woodhouse
It doesn't need to wait until no commands are pending anyway -- it only needs to wait until the scan is finished.

2008-01-28libertas: rework event subscriptionHolger Schurig
This patch moves re-works the implementation of event subscription via debugfs. For this: * it tells cmd.c and cmdresp.c about CMD_802_11_SUBSCRIBE_EVENT * removes lots of low-level cmd stuff from debugfs.c * create unified functions to read/write snr, rssi, bcnmiss and failcount * introduces #define's for subscription event bitmask values * add a function to search for a specific element in an IE (a.k.a. TLV) * add a function to find out the size of the TLV. This is needed because lbs_prepare_and_send_command() has an argument for a data buffer, but not for it's lengths and TLVs can be, by definition, vary in size. * fix a bug where it was not possible to disable an event Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

This patch unifies the namespace of variables, functions defines and structures. It does: - rename libertas_XXX to lbs_XXX - rename LIBERTAS_XXX to lbs_XXX - rename wlan_XXX to lbs_XXX - rename WLAN_XXX to LBS_XXX (but only those that were defined in libertas-local *.h files, e.g. not defines from net/ieee80211.h) While passing, I fixed some checkpatch.pl errors too.

2007-10-10[PATCH] libertas link error due to gcc `smartness'Geert Uytterhoeven
Some versions of gcc replace strstr() calls with a single-character `needle' parameter by strchr() behind our back. This causes a link error if strchr() is defined as an inline function in <asm/string.h> (e.g. on m68k): | drivers/built-in.o: In function `libertas_parse_chan': | linux/drivers/net/wireless/libertas/debugfs.c:209: undefined reference to `strchr' | drivers/built-in.o: In function `libertas_parse_ssid': | linux/drivers/net/wireless/libertas/debugfs.c:260: undefined reference to `strchr' Avoid this by explicitly calling strchr() instead. Also include <linux/string.h>, because this file calls lots of str*() routines.

2007-10-10[PATCH] libertas: remove bss_descriptior->networktsfHolger Schurig
This value was parsed out, but then nowhere used ... except in some debugfs output. I can't imagine anyone wanting to use this value for anything real (as no other driver exports it), so bye-bye.

2007-10-10[PATCH] libertas: remove a hundred CMD_RET_xxx definitionsHolger Schurig
types.h contains the same amount of CMD_RET_xxx and CMD_xxx definitions. They contains the same info: the firmware command opcode and, when the firmware sends back a result, the command opcode ORed with 0x8000. Having the same data twice in the source code is redundant and can lead to errors (e.g. if you update or delete only one instance). This patch removed all CMD_RET_xxx definitions and introduces a simple CMD_RET() macro. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: John W.

2007-06-11[PATCH] libertas: remove unused variables in wlan_dev_tHolger Schurig
Actually, this patch removev wlan_dev_t totally and puts the used variables of it directly into wlan_private. That reduces one level of indirection and looks a little bit simpler. It's now "priv->card" and not "priv->wlan_dev.card" and "priv->dev" instead of "priv->wlan_dev.netdev" Changed two occurences of "((wlan_private *) dev->priv)->wlan_dev.netdev" into "dev", because I didn't see the point in doing pointer-ping-pong. The variables "ioport", "upld_rcv" and "upld_type" where unused. They have been removed. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: John W.
