* net/ieee80211 -> drivers/net/ipw2x00/libipw_* renameJohn W. Linville2008-11-21
| | | | | | | | The old ieee80211 code only remains as a support library for the ipw2100 and ipw2200 drivers. So, move the code and rename it appropriately to reflects it's true purpose and status. Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | These bits are shared already between ipw2x00 and hostap, and could probably be shared both more cleanly and with other drivers. This commit simply relocates the code to lib80211 and adjusts the drivers appropriately. Signed-off-by: John W. Linville <linville@tuxdriver.com>

* make ieee80211 invisibleJohannes Berg2008-10-31
| | | | | | | | | | | | | | | This makes CONFIG_IEEE80211 invisible. The drivers that require it (ipw2100, ipw2200, hostap) select it, and everybody else really shouldn't even think about using it. Also, since there really is no point in compiling anything without crypto support these days, remove the crypto options and just enable them, leaving only the debugging option which only shows up when a driver is select that requires it. This makes it hard to enable, but most people wouldn't want to anyway.

* wext: Emit event stream entries correctly when compat.David S. Miller2008-06-16
| | | | | | | | | | | | | | | | | | | | | | Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_stream_add_*(), and use it to size the event and pointer lengths correctly depending upon whether IW_REQUEST_FLAG_COMPAT is set or not. 4) The mechanical transformations to the drivers and wireless stack bits to get the iw_request_info passed down into the routines modified in #3. Also, explicit references to IW_EV_LCP_LEN are replaced with iwe_stream_lcp_len(info). With a lot of help and bug fixes from Masakazu Mokuno. Signed-off-by: David S. Miller <davem@davemloft.net>
* mac80211: use hardware flags for signal/noise unitsBruno Randolf2008-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

| * [NET]: Undo code bloat in hot paths due to print_mac().David S. Miller2008-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If print_mac() is used inside of a pr_debug() the compiler can't see that the call is redundant so still performs it even of pr_debug() ends up being a nop. So don't use print_mac() in such cases in hot code paths, use MAC_FMT et al. instead. As noted by Joe Perches, pr_debug() could be modified to handle this better, but that is a change to an interface used by the entire kernel and thus needs to be validated carefully. This here is thus the less risky fix for 2.6.25 Signed-off-by: David S. Miller <davem@davemloft.net>

This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke.

* [NET]: Make /proc/net per network namespaceEric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.
