- don't use 'qemu -serial mon:stdio' anymore as it no longer works as
expected
- use "bash -l" with [terminal] to read user's profile configuration,
e.g., PATH settings
- added missing boot modules and cap quotas
As a result of the API change the memory handling could be simplified.
Since the Block session dataspace is now directly used for DMA, we
actually only have to provide the memory for setting up PRP lists for
large requests (for the moment more than 8 KiB of data).
As we limit the maximum data transfer length to 2 MiB, we get by with
just a page per request. Those memory is allocated beforehand for the
maximum number of I/O requests, which got bumbed to 512 entries. Since
not all NVMe controllers support such large a maximum data transfer
length and this many entries, especially older ones, the values are
capped according to the properties of the controller during
initialization. (The memory demands of the component are around 3 MiB
due to setting up for the common case, even if a particular controller
is only able to make use of less.)
(Although there are controllers whose maximum memory page size is more
than 4K, the driver is hardcoded to solely use 4K pages.)
In addition to those changes, the driver now supports the 'SYNC' and
'TRIM' operations of the Block session by using the NVMe 'FLUSH' and
'WRITE_ZEROS' commands.
Fixes#3702.
The update modification timestamp is implemented as one-shot where
the caller is expected to try again if the first attempt failed (see
current libc implementation). So the message is misleading as further
attempts might succeed.
Issue #3713.
This patch fixes a regression with run/log_core introduced by
2064ffd64b nova: support multidimensional affinity space
The run tool uses a log message 'run_boot_string' to detect successful
boot as well as to detect unexpected reboots. This message should never
be logged twice and, thus, should not be part of the core_log. The patch
mentioned above moved the former run_boot_string after the core_log
initialization.
The tar vfs plugin returns an inode value of zero and a type directory
for null records, which wrongly triggers the file-system loop detection
of the find utility. This patch returns the node pointer as inode value
instead, which is a unique value.
Fixes#3695
This patch changes the 'Single_file_system' to return NO_PERM only if
the to-be-unlinked file corresponds to the single file. This way, a
<rom> co-mounted with a <ram> file-system does not stand in the way of
unlinking files from the <ram>. The concrete symptom occurred the
following scenario:
<vfs>
<dir name="home">
<ram/>
<rom name="..."/>
</dir>
</vfs>
The following sequence of commands wrongly resulted in "Operation not
permitted":
$ mkdir -p /home/a/b/c
$ rm -f /home/a/b/c/d
In this case, rm should not fail (unlink should return ENOENT)
Fixes#3690
When updating the domain object of interfaces that stay with the same domain
during a reconfiguration, until now, the normal "detach raw" function was used.
This caused the old domain object to discard a dynamic IP config as all
interfaces detached. This caused interfaces also to discard network links
established with the old configuration although it wasn't necessary. Thus, now
we use a dedicated "detach" in case that an interface actually stays with its
domain. This new "detach" doesn't decrease the interface counter of the domain,
so, it'll not discard its dynamic IP config. If, however, during a
reconfiguration, there's no interface calling this function (all interfaces
move to another or no domain), the dynamic IP config is still discarded as
expected.
Fixes#3686
Until now, the DHCP client was called also for DHCP requests when an interface
had a domain but yet no IP config. Now, an interface distinguishes between DHCP
requests and replies first and then accordingly calls the DHCP server or the
DHCP client if they're available. This also prevents that the DHCP client has
to handle packet headers other than that of DHCP.
Fixes#3681
Let the DHCP client be a constructible member of Interface that is constructed
only as long as the interface is attached to a domain with a dynamic IP config.
This prevents DHCP client timeouts from a period with dynamic IP config to
trigger after a reconfiguration to a static IP config. Furthermore, handle
DHCP-reply packets at an interface only when the DHCP client its constructed.
Otherwise drop such packets.

This commit fixes the following issues regarding cache maintainance
under ARM:
* read out I-, and D-cache line size at runtime and use the correct one
* remove 'update_data_region' call from unprivileged syscalls
* rename 'update_instr_region' syscall to 'cache_coherent_region' to
reflect what it doing, namely make I-, and D-cache coherent
* restrict 'cache_coherent_region' syscall to one page at a time
* lookup the region given in a 'cache_coherent_region' syscall in the
page-table of the PD to prevent machine exceptions in the kernel
* only clean D-cache lines, do not invalidate them when pages where
added on Cortex-A8 and ARMv6 (MMU sees phys. memory here)
* remove unused code relicts of cache maintainance
In addition it introduces per architecture memory clearance functions
used by core, when preparing new dataspaces. Thereby, it optimizes:
* on ARMv7 using per-word assignments
* on ARMv8 using cacheline zeroing
* on x86_64 using 'rept stosq' assembler instruction
Fix#3685
This depot package is the runtime for rtc_drv and system_rtc server with
coordinated update of system and hardware RTC via reports. It replaces
drivers_rtc which was never freestanding drivers package and, therefore,
has to be accompanied with a running platform_drv etc.
Fixes#3680
- use two disks with two partitions each
- one disk uses MBR and one GPT
- connect one 'part_block' to each disk
- run 'block_tester' and 'test-block-client' connecting to one partiion
on each disk
- x86 uses 'ahci_drv' as disk back-end, Linux 'lx_block'
- on autopilot enable for Qemu only
