2016-10-24char: replace avail_connectionsMarc-André Lureau1-1/+0
No need to count the users of a CharDriverState, it can rely on the fact of whether there is a CharBackend associated or if there is enough space in the muxer. Simplify and fold chr_mux_new_fe() in qemu_chr_fe_init() since there is a single user now. Also switch from fprintf to raising error instead.

2016-10-24char: move front end handlers in CharBackendMarc-André Lureau1-5/+7
Since the hanlders are associated with a CharBackend, rather than the CharDriverState, it is more appropriate to store in CharBackend. This avoids the handler copy dance in qemu_chr_fe_set_handlers() then mux_chr_update_read_handler(), by storing the CharBackend pointer directly. Also a mux CharDriver should go through mux->backends[focused], since chr->be will stay NULL. Before that, it was possible to call chr->handler by mistake with surprising results, for ex through qemu_chr_be_can_write(), which would result in calling the last set handler front end, not the one with focus.

2016-07-12hw/bt: Don't use cpu_to_*w() and *_to_cpup()Peter Maydell2-13/+9
Don't use cpu_to_*w() and *_to_cpup() to do byte-swapped loads and stores; instead use ld*_p() and st*_p() which correctly handle misaligned accesses. Bring the HNDL() macro into line with how we deal with PARAMHANDLE(), by using cpu_to_le16() rather than an ifdef HOST_WORDS_BIGENDIAN.

2016-05-29bt: rewrite csrhci_write to avoid out-of-bounds writesPaolo Bonzini1-21/+46
The usage of INT_MAX in this function confuses Coverity. I think the defect is bogus, however there is no protection against getting more than sizeof(s->inpkt) bytes from the character device backend. Rewrite the function to only fill in as much data as needed from buf into s->inpkt. The plen variable is replaced by a simple state machine and there is no need anymore to shift contents to the beginning of s->inpkt. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-03-22Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah1-2/+2
This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster1-0/+1
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-11-06bt: fix use of uninitialized variable seqlenPaolo Bonzini1-9/+20
sdp_svc_match, sdp_attr_match and sdp_svc_attr_match read the last argument. The only sensible way to change the code is to make that last argument "len" instead of "seqlen" which is the length of a subsequence in the previous "if" branch. To make the structure of the code clearer, use "else" instead of "else if". Reported by Coverity. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

2015-09-25bt: remove muldiv64()Laurent Vivier1-2/+2
Originally, timers were ticks based, and it made sense to add ticks to current time to know when to trigger an alarm. But since commit: 7447545 change all other clock references to use nanosecond resolution accessors All timers use nanoseconds and we need to convert ticks to nanoseconds. As get_ticks_per_sec() is 10^9, a = muldiv64(b, get_ticks_per_sec(), 100); y = muldiv64(x, get_ticks_per_sec(), 1000000); can be converted to a = b * 10000000; y = x * 1000; Signed-off-by: Laurent Vivier <lvivier@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>

2015-04-28bt-sdp: fix broken uuids power-of-2 calculationStefan Hajnoczi1-1/+1
The binary search in sdp_uuid_match() only works when the number of elements to search is a power of two. lo = record->uuid; hi = record->uuids; while (hi >>= 1) if (lo[hi] <= val) lo += hi; return *lo == val; I noticed that the record->uuids calculation in sdp_service_record_build() was suspect: record->uuids = 1 << ffs(record->uuids - 1); Unlike most ffs(val) - 1 users, the expression is ffs(val - 1)! Actually ffs() is the wrong function to use for power-of-2. Use pow2ceil() to achieve the correct effect. Now the record->uuid[] array is sized correctly and the binary search in sdp_uuid_match() should work. I'm not sure how to run/test this code.
