* [PATCH] wireless: move zd1201 where it belongsPavel Machek2006-06-05
| | | | | | | | | zd1201 is wifi adapter, yet it is hiding in drivers/usb/net where noone can find it. This moves Kconfig/Makefile zd1201 to the right place. Signed-off-by: Pavel Machek <pavel@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* [PATCH] softmac: Fix handling of authentication failureDaniel Drake2006-06-05
| | | | | | | | | | | | | | | | | | | | My router blew up earlier, but exhibited some interesting behaviour during its dying moments. It was broadcasting beacons but wouldn't respond to any authentication requests. I noticed that softmac wasn't playing nice with this, as I couldn't make it try to connect to other networks after it had timed out authenticating to my ill router. To resolve this, I modified the softmac event/notify API to pass the event code to the callback, so that callbacks being notified from IEEE80211SOFTMAC_EVENT_ANY masks can make some judgement. In this case, the ieee80211softmac_assoc callback needs to make a decision based upon whether the association passed or failed.

* [PATCH] softmac: complete shared key authenticationDaniel Drake2006-06-05
| | | | | | | | | | | | | | | | | | This patch finishes of the partially-complete shared key authentication implementation in softmac. The complication here is that we need to encrypt a management frame during the authentication process. I don't think there are any other scenarios where this would have to happen. To get around this without causing too many headaches, we decided to just use software encryption for this frame. The softmac config option now selects IEEE80211_CRYPT_WEP so that we can ensure this available. This also involved a modification to some otherwise unused ieee80211 API.

| | * [SCSI] mptspi: reset handler shouldn't be called for other bus protocolsJames Bottomley2006-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All registered reset callback handlers are called during reset processing. The mptspi modules has its own reset callback handler, just recently added for issuing domain validation after host reset. If either the mptsas or mptfc driver are loaded, this callback could be called. Thus resulting in domain validation being issued for sas or fibre end devices. Fix this by having mptbase.c check the bus type against the driver type and only call the reset handler if they match (or if it's a non-bus specific reset handler).

We don't deal with this, so currently, when asked to enable IRQ 64, we will enable IRQ 56 instead. The only interrupts >= 64 are the thread interrupt sources, and there are no in-tree users of those yet, so this is fortunately not a big problem, but this needs fixing anyway.

Stepping A1 of the ixp2350, which has a PRODUCT_ID of 0x401, has '02' in the lower byte of processor_id, while A2, with a PRODUCT_ID of 0x402, has '04' in the lower byte of processor_id. So, to check for >= A2, we really need to check the lower byte of processor_id against >= 4.

Firstly, "offslab_limit" is a global variable while it should either be calculated in situ or should be passed in as a parameter. Secondly, the more serious problem with it is that the condition for calculating it: if (!(OFF_SLAB(sizes->cs_cachep))) { offslab_limit = sizes->cs_size - sizeof(struct slab); offslab_limit /= sizeof(kmem_bufctl_t); is in total disconnect with the condition that makes use of it: /* More than offslab_limit objects will cause problems */ if ((flags & CFLGS_OFF_SLAB) && num > offslab_limit) break; but due to offslab_limit being a global variable this breakage was hidden. Up until lockdep came along and perturbed the slab sizes sufficiently so that the first off-slab cache would still see a (non-calculated) zero value for offslab_limit and would panic with: kmem_cache_create: couldn't create cache size-512. Call Trace: [<ffffffff8020a5b9>] show_trace+0x96/0x1c8 [<ffffffff8020a8f0>] dump_stack+0x13/0x15 [<ffffffff8022994f>] panic+0x39/0x21a [<ffffffff80270814>] kmem_cache_create+0x5a0/0x5d0 [<ffffffff80aced62>] kmem_cache_init+0x193/0x379 [<ffffffff80abf779>] start_kernel+0x17f/0x218 [<ffffffff80abf263>] _sinittext+0x263/0x26a Kernel panic - not syncing: kmem_cache_create(): failed to create slab `size-512' Paolo Ornati's config on x86_64 managed to trigger it. The fix is to move the calculation to the place that makes use of it. This also makes slab.o 54 bytes smaller. Btw., the check itself is quite silly. Its intention is to test whether the number of objects per slab would be higher than the number of slab control pointers possible. In theory it could be triggered: if someone tried to allocate 4-byte objects cache and explicitly requested with CFLGS_OFF_SLAB. So i kept the check. Out of historic interest i checked how old this bug was and it's ancient, 10 years old! It is the oldest hidden and then truly triggering bugs i ever saw being fixed in the kernel!

| | * | | [MIPS] Fix marking buddy of pte global for MIPS32 w/36-bit physical addressSergei Shtylyov2006-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of CONFIG_64BIT_PHYS_ADDR, set_pte() and pte_clear() functions only set _PAGE_GLOBAL bit in the pte_low field of the buddy PTEs, forgetting to propagate ito to pte_high. Thus, the both pages might not really be made global for the CPU (since it AND's the G-bit of the odd / even PTEs together to decide whether they're global or not). Thus, if only a single page is allocated via vmalloc() or ioremap(), it's not really global for CPU (and it must be, since this is kernel mapping), and thus its ASID is compared against the current process' one -- so, we'll get into trouble sooner or later... Also, pte_none() will fail on global pages because _PAGE_GLOBAL bit is set in both pte_low and pte_high, and pte_val() will return u64 value consisting of those fields concateneted.
