2015-09-09ARM: swpan: fix nwfpe for uaccess changesRussell King1-1/+2
NWFPE needs to access userspace to check whether the next instruction is another FP instruction. Allow userspace access for this read. Signed-off-by: Russell King <[email protected]>
2015-08-26ARM: software-based priviledged-no-access supportRussell King7-8/+125
Provide a software-based implementation of the priviledged no access support found in ARMv8.1. Userspace pages are mapped using a different domain number from the kernel and IO mappings. If we switch the user domain to "no access" when we enter the kernel, we can prevent the kernel from touching userspace. However, the kernel needs to be able to access userspace via the various user accessor functions. With the wrapping in the previous patch, we can temporarily enable access when the kernel needs user access, and re-disable it afterwards. This allows us to trap non-intended accesses to userspace, eg, caused by an inadvertent dereference of the LIST_POISON* values, which, with appropriate user mappings setup, can be made to succeed. This in turn can allow use-after-free bugs to be further exploited than would otherwise be possible. Signed-off-by: Russell King <[email protected]>
2015-08-26ARM: entry: provide uaccess assembly macro hooksRussell King11-11/+55
Provide hooks into the kernel entry and exit paths to permit control of userspace visibility to the kernel. The intended use is: - on entry to kernel from user, uaccess_disable will be called to disable userspace visibility - on exit from kernel to user, uaccess_enable will be called to enable userspace visibility - on entry from a kernel exception, uaccess_save_and_disable will be called to save the current userspace visibility setting, and disable access - on exit from a kernel exception, uaccess_restore will be called to restore the userspace visibility as it was before the exception occurred. These hooks allows us to keep userspace visibility disabled for the vast majority of the kernel, except for localised regions where we want to explicitly access userspace.

2015-08-26ARM: entry: get rid of multiple macro definitionsRussell King1-65/+44
The following structure is just asking for trouble: #ifdef CONFIG_symbol .macro foo ... .endm .macro bar ... .endm .macro baz ... .endm #else .macro foo ... .endm .macro bar ... .endm #ifdef CONFIG_symbol2 .macro baz ... .endm #else .macro baz ... .endm #endif #endif such as one defintion being updated, but the other definitions miss out. Where the contents of a macro needs to be conditional, the hint is in the first clause of this very sentence. "contents" "conditional". Not multiple separate definitions, especially not when much of the macro is the same between different configs. This patch fixes this bad style, which had caused the Thumb2 code to miss-out on the uaccess updates. Signed-off-by: Russell King <[email protected]>
2015-08-25ARM: uaccess: provide uaccess_save_and_enable() and uaccess_restore()Russell King7-21/+97
Provide uaccess_save_and_enable() and uaccess_restore() to permit control of userspace visibility to the kernel, and hook these into the appropriate places in the kernel where we need to access userspace. Signed-off-by: Russell King <[email protected]>
2015-08-25ARM: mm: improve do_ldrd_abort macroRussell King4-11/+11
Improve the do_ldrd_abort macro code - firstly, it inefficiently checks for the LDRD encoding by doing a multi-stage test of various bits. This can be simplified by generating a mask, bitmasking the instruction and then comparing the result. Secondly, we want to be able to test the result rather than branching to do_DataAbort, so remove the branch at the end and rename the macro to 'teq_ldrd' to reflect it's new usage. teq_ldrd macro returns 'eq' if the instruction was a LDRD.

2015-08-21ARM: domains: remove DOMAIN_TABLERussell King1-3/+0
DOMAIN_TABLE is not used; in any case, it aliases to the kernel domain. Remove this definition. Signed-off-by: Russell King <[email protected]>
2015-08-21ARM: domains: keep vectors in separate domainRussell King4-3/+16
Keep the machine vectors in its own domain to avoid software based user access control from making the vector code inaccessible, and thereby deadlocking the machine. Signed-off-by: Russell King <[email protected]>
2015-08-21ARM: domains: get rid of manager mode for user domainRussell King2-2/+1
Since we switched to early trap initialisation in 94e5a85b3be0 ("ARM: earlier initialization of vectors page") we haven't been writing directly to the vectors page, and so there's no need for this domain to be in manager mode. Switch it to client mode. Signed-off-by: Russell King <[email protected]>
2015-08-21ARM: domains: move initial domain setting value to asm/domains.hRussell King2-4/+7
Signed-off-by: Russell King <[email protected]>
2015-08-21ARM: domains: provide domain_mask()Russell King1-2/+3
Provide a macro to generate the mask for a domain, rather than using domain_val(, DOMAIN_MANAGER) which won't work when CPU_USE_DOMAINS is turned off. Signed-off-by: Russell King <[email protected]>
2015-08-21ARM: domains: switch to keeping domain value in registerRussell King4-11/+27
Rather than modifying both the domain access control register and our per-thread copy, modify only the domain access control register, and use the per-thread copy to save and restore the register over context switches. We can also avoid the explicit initialisation of the init thread_info structure. This allows us to avoid needing to gain access to the thread information at the uaccess control sites.

2015-07-04bluetooth: fix list handlingLinus Torvalds2-2/+3
Commit 835a6a2f8603 ("Bluetooth: Stop sabotaging list poisoning") thought that the code was sabotaging the list poisoning when NULL'ing out the list pointers and removed it. But what was going on was that the bluetooth code was using NULL pointers for the list as a way to mark it empty, and that commit just broke it (and replaced the test with NULL with a "list_empty()" test on a uninitialized list instead, breaking things even further). So fix it all up to use the regular and real list_empty() handling (which does not use NULL, but a pointer to itself), also making sure to initialize the list properly (the previous NULL case was initialized implicitly by the session being allocated with kzalloc()) This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong An.

git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull SCSI target updates from Nicholas Bellinger: "It's been a busy development cycle for target-core in a number of different areas. The fabric API usage for se_node_acl allocation is now within target-core code, dropping the external API callers for all fabric drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lockless code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (76 commits) target: Bump core version to v5.0 target: remove target_core_configfs.h target: remove unused TARGET_CORE_CONFIG_ROOT define target: consolidate version defines target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: simplify UNMAP handling target: replace se_cmd->execute_rw with a protocol_data field target/user: Fix inconsistent kmap_atomic/kunmap_atomic target: Send UA when changing LUN inventory target: Send UA upon LUN RESET tmr completion target: Send UA on ALUA target port group change target: Convert se_lun->lun_deve_lock to normal spinlock target: use 'se_dev_entry' when allocating UAs target: Remove 'ua_nacl' pointer from se_ua structure target_core_alua: Correct UA handling when switching states xen-scsiback: Fix compile warning for 64-bit LUN target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target: use 64-bit LUNs target: Drop duplicate + unused se_dev_check_wce target: Drop unnecessary core_tpg_register TFO parameter ...
