2020-09-01block: always link with zlibPaolo Bonzini1-2/+2
The qcow2 driver needs the zlib dependency. While emulators provided it through the migration code, this is not true of the tools. Move the dependency from the qcow1 rule directly into block_ss so that it is included unconditionally. Fixes build with --disable-qcow1.

2020-08-31usb: fix setup_len init (CVE-2020-14364)Gerd Hoffmann1-6/+10
Store calculated setup_len in a local variable, verify it, and only write it to the struct (USBDevice->setup_len) in case it passed the sanity checks. This prevents other code (do_token_{in,out} functions specifically) from working with invalid USBDevice->setup_len values and overrunning the USBDevice->setup_buf[] buffer.

2020-08-31hw/usb: Add U2F device autoscan to passthru modeCésar Belley3-14/+110
This patch adds an autoscan to let u2f-passthru choose the first U2F device it finds. The autoscan is performed using libudev with an enumeration of all the hidraw devices present on the host. The first device which happens to be a U2F device is taken to do the passtru.

2020-08-31hw/usb: Add U2F key emulated modeCésar Belley1-0/+405
This patch adds the U2F key emulated mode. The emulated mode consists of completely emulating the behavior of a U2F device through software part. Libu2f-emu is used for that. The emulated mode is associated with a device inheriting from u2f-key base. To work, an emulated U2F device must have differents elements which can be given in different ways. This is detailed in docs/u2f.txt. The Ephemeral one is the simplest way to configure, it lets the device generate all the elements it needs for a single use of the lifetime of the device: qemu -usb -device u2f-emulated For more information about libu2f-emu see this page: https://github.com/MattGorko/libu2f-emu.

2020-08-31hw/usb: Add U2F key passthru modeCésar Belley1-0/+423
This patch adds the U2F key pass-through mode. The pass-through mode consists of passing all requests made from the guest to the physical security key connected to the host machine and vice versa. In addition, the dedicated pass-through allows to have a U2F security key shared on several guests which is not possible with a simple host device assignment pass-through. The pass-through mode is associated with a device inheriting from u2f-key base. To work, it needs the path to a U2F hidraw, obtained from the Qemu command line, and passed by the user: qemu -usb -device u2f-passthru,hidraw=/dev/hidrawX Autoscan and U2F compatibility checking features are given at the end of the patch series.

2020-08-31hw/usb: Add U2F key base class implementationCésar Belley1-0/+352
This patch adds the U2F key base class implementation. The U2F key base mainly takes care of the HID interfacing with guest. On the one hand, it retrieves the guest U2FHID packets and transmits them to the variant associated according to the mode: pass-through or emulated. On the other hand, it provides the public API used by its variants to send U2FHID packets to the guest.

Used to group the common characteristics, this device class will be inherited by its two variants, corresponding to the two modes: passthrough and emulated This prepares the U2F devices hierarchy which is as follow: USB device -> u2f-key -> {u2f-passthru, u2f-emulated}.

2020-08-28linux-user: Add support for utimensat_time64() and semtimedop_time64()Filip Bozuta1-11/+53
This patch introduces functionality for following time64 syscalls: *utimensat_time64() int utimensat(int dirfd, const char *pathname, const struct timespec times[2], int flags); -- change file timestamps with nanosecond precision -- man page: https://man7.org/linux/man-pages/man2/utimensat.2.html *semtimedop_time64() int semtimedop(int semid, struct sembuf *sops, size_t nsops, const struct timespec *timeout); -- System V semaphore operations -- man page: https://www.man7.org/linux/man-pages/man2/semtimedop.2.html Implementation notes: Syscall 'utimensat_time64()' is implemented in similar way as its regular variants only difference being that time64 converting function is used to convert values of 'struct timespec' between host and target ('target_to_host_timespec64()'). For syscall 'semtimedop_time64()' and additional argument is added in function 'do_semtimedop()' through which the aproppriate 'struct timespec' converting function is called (false for regular target_to_host_timespec() and true for target_to_host_timespec64()). For 'do_ipc()' a check was added as that additional argument: 'TARGET_ABI_BITS == 64'.

This patch implements functionality for following time64 syscall: *clock_nanosleep_time64() This is a year 2038 safe vairant of syscall: int clock_nanosleep(clockid_t clockid, int flags, const struct timespec *request, struct timespec *remain) --high-resolution sleep with specifiable clock-- man page: https://man7.org/linux/man-pages/man2/clock_nanosleep.2.html *clock_adjtime64() This is a year 2038 safe variant of syscall: int clock_adjtime(clockid_t clk_id, struct timex *buf) --tune kernel clock-- man page: https://man7.org/linux/man-pages/man2/clock_adjtime.2.html Implementation notes: Syscall 'clock_nanosleep_time64()' was implemented similarly to syscall 'clock_nanosleep()' except that 'host_to_target_timespec64()' and 'target_to_host_timespec64()' were used instead of the regular 'host_to_target_timespec()' and 'target_to_host_timespec()'. For 'clock_adjtime64()' a 64-bit target kernel version of 'struct timex' was defined in 'syscall_defs.h': 'struct target__kernel_timex'. This type was used to convert the values of 64-bit timex type between host and target. For this purpose a 64-bit timex converting functions 'target_to_host_timex64()' and 'host_to_target_timex64()'. An existing function 'copy_to_user_timeval64()' was used to convert the field 'time' which if of type 'struct timeval' from host to target. Function 'copy_from_user_timveal64()' was added in this patch and used to convert the 'time' field from target to host.

2020-08-28virtiofsd: probe unshare(CLONE_FS) and print an errorStefan Hajnoczi1-0/+16
An assertion failure is raised during request processing if unshare(CLONE_FS) fails. Implement a probe at startup so the problem can be detected right away. Unfortunately Docker/Moby does not include unshare in the seccomp.json list unless CAP_SYS_ADMIN is given. Other seccomp.json lists always include unshare (e.g. podman is unaffected): https://raw.githubusercontent.com/seccomp/containers-golang/master/seccomp.json Use "docker run --security-opt seccomp=path/to/seccomp.json ..." if the default seccomp.json is missing unshare.

2020-08-28virtiofsd: drop CAP_DAC_READ_SEARCHStefan Hajnoczi1-1/+0
virtiofsd does not need CAP_DAC_READ_SEARCH because it already has the more powerful CAP_DAC_OVERRIDE. Drop it from the list of capabilities. This is important because container runtimes may not include CAP_DAC_READ_SEARCH by default. This patch allows virtiofsd to reduce its capabilities when running inside a Docker container. Note that CAP_DAC_READ_SEARCH may be necessary again in the future if virtiofsd starts using open_by_handle_at(2).

2020-08-28virtiofsd: Disable remote posix locks by defaultVivek Goyal2-2/+2
Right now we enable remote posix locks by default. That means when guest does a posix lock it sends request to server (virtiofsd). But currently we only support non-blocking posix lock and return -EOPNOTSUPP for blocking version. This means that existing applications which are doing blocking posix locks get -EOPNOTSUPP and fail. To avoid this, people have been running virtiosd with option "-o no_posix_lock". For new users it is still a surprise and trial and error takes them to this option. Given posix lock implementation is not complete in virtiofsd, disable it by default. This means that posix locks will work with-in applications in a guest but not across guests. Anyway we don't support sharing filesystem among different guests yet in virtiofs so this should not lead to any kind of surprise or regression and will make life little easier for virtiofs users.

2020-08-28migration: tls: fix memory leak in migration_tls_get_credsZhenyu Ye1-1/+0
Currently migration_tls_get_creds() adds the reference of creds but there was no place to unref it. So the OBJECT(creds) will never be freed and result in memory leak. The leak stack: Direct leak of 104 byte(s) in 1 object(s) allocated from: #0 0xffffa88bd20b in __interceptor_malloc (/usr/lib64/libasan.so.4+0xd320b) #1 0xffffa7f0cb1b in g_malloc (/usr/lib64/libglib-2.0.so.0+0x58b1b) #2 0x14b58cb in object_new_with_type qom/object.c:634 #3 0x14b597b in object_new qom/object.c:645 #4 0x14c0e4f in user_creatable_add_type qom/object_interfaces.c:59 #5 0x141c78b in qmp_object_add qom/qom-qmp-cmds.c:312 #6 0x140e513 in qmp_marshal_object_add qapi/qapi-commands-qom.c:279 #7 0x176ba97 in do_qmp_dispatch qapi/qmp-dispatch.c:165 #8 0x176bee7 in qmp_dispatch qapi/qmp-dispatch.c:208 #9 0x136e337 in monitor_qmp_dispatch monitor/qmp.c:150 #10 0x136eae3 in monitor_qmp_bh_dispatcher monitor/qmp.c:239 #11 0x1852e93 in aio_bh_call util/async.c:89 #12 0x18531b7 in aio_bh_poll util/async.c:117 #13 0x18616bf in aio_dispatch util/aio-posix.c:459 #14 0x1853f37 in aio_ctx_dispatch util/async.c:268 #15 0xffffa7f06a7b in g_main_context_dispatch (/usr/lib64/libglib-2.0.so.0+0x52a7b) Since we're fine to use the borrowed reference when using the creds, so just remove the object_ref() in migration_tls_get_creds().
