2007-04-25[SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}Arnaldo Carvalho de Melo
To clearly state the intent of copying from linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2007-04-25[SK_BUFF]: Convert skb->end to sk_buff_data_tArnaldo Carvalho de Melo
Now to convert the last one, skb->data, that will allow many simplifications and removal of some of the offset helpers. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

2007-04-25[SK_BUFF]: unions of just one member don't get anything done, kill themArnaldo Carvalho de Melo
Renaming skb->h to skb->transport_header, skb->nh to skb->network_header and skb->mac to skb->mac_header, to match the names of the associated helpers (skb[_[re]set]_{transport,network,mac}_header).

2007-04-25[SK_BUFF]: Introduce skb_reset_network_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[SK_BUFF]: Introduce skb_mac_header()Arnaldo Carvalho de Melo
For the places where we need a pointer to the mac header, it is still legal to touch skb->mac.raw directly if just adding to, subtracting from or setting it to another layer header. This one also converts some more cases to skb_reset_mac_header() that my regex missed as it had no spaces before nor after '=', ugh.

2007-04-10[PATCH] bcm43xx: Fix PPC machine checks and match loopback gain specsLarry Finger

2007-04-10[PATCH] bcm43xx: Fix 802.11b/g scan limits to match regulatory reqsLarry Finger
In 802.11b/g mode, bcm43xx actively scans channels 1-14 no matter what locale has been set, either in the sprom or by the locale option. This behaviorviolates regulatory rules everywhere in the world except Japan. This patch changes the default range to the correct value if the locale has been set, and to channels 1-13 if no locale has been set.

2007-04-10[PATCH] zd1211rw: Fix E2P_PHY_REG patchingDaniel Drake
Due to conflicting/confusing defines in the vendor driver, we were reading E2P_PHY_REG from the wrong location. CR157 patching was slightly incorrect in that the vendor driver only patches in an 8-bit value, whereas we were patching 24 bits. Additionally, CR157 patching was happening on both zd1211 and zd1211b, but this should only happen on zd1211.

2007-04-10[PATCH] zd1211rw: Reject AL2230S devicesDaniel Drake
zd1211rw currently detects AL2230S-based devices as AL2230, and hence programs the RF incorrectly. Transmit silently fails on this misconfiguration. After this patch, AL2230S devices are rejected with an error message, to avoid any confusion with an apparent driver bug. Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.

Recent changes in the specs that were introduced in commit 740ac4fb08866d702be90f167665d03759bd27d0 were incorrect and resulted in machine check errors on the PPC architecture for G PHY's with a revision number equal to 1.

2007-03-16[PATCH] bcm43xx: MANUALWLAN fixesLarry Finger
During testing of bcm43xx interference mitigation, two problems were discovered: (1) When the MANUALWLAN mode was set, routines _stack_save and _stack_restore generated assertions that were traced to saving ILT registers with addresses > 0xFFF. This problem was fixed by adding one bit to the field used for the offset, and subtracting one bit from the space used for the id. (2) In MANUALWLAN mode, the IRQ XMIT errors are generated. The cause of these errors has not yet been located. Any suggestions on debugging this problem would be greatly appreciated.

2007-02-14[PATCH] bcm43xx: OFDM fix for rev 1 cardsLarry Finger
Nearly all of the writes to the bcm43xx internal lookup tables (ilt) involve 16-bit quantities. Accordingly, the ilt_write routine was coded to pass a u16 value. For one early GPHY chip, 32-bit quantities are needed. For those writes, the value was clipped to 16 bits. This patch adds an ilt_write32 routine that receives a 32-bit quantity and writes it to the appropriate locations. Signed-off-by: Larry Finger<Larry.Finger@lwfinger.net> Signed-off-by: John W.

2007-02-14[PATCH] prism54: correct assignment of DOT1XENABLE in WE-19 codepathsDan Williams
Correct assignment of DOT1XENABLE in WE-19 codepaths. RX_UNENCRYPTED_EAPOL = 1 really means setting DOT1XENABLE _off_, and vice versa. The original WE-19 patch erroneously reversed that.

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
