a77c073797 arch/: Fix an interlock that was broken by commit 641a98a434 in all implementations of up_sigdeliver. 2019-02-03 17:14:32 -06:00

641a98a434 arch/: The saved return register state is available on the user stack. Thic commit reorders some logic so that certain, critical registers are preserved in the TCB. This does not make the logic 100% secure, but does prevent some obvious things. sched/signal/sig_delivery: Add a flag to the TCB to indicate that we are in a signal handler. Use this flag to assure that a there a never attempts to nest signal handling operations on a thread. This was guaranteed before but when locking of pre-emption during signal delivering was eliminated in a previous commit, there was a remote possibility of an attempt to do nested signal handling. This flag assures that there is only one signal handled at a time. 2019-02-03 15:29:47 -06:00

df64811269 up_initialize(): As noted by Roland Takacs in Bitbucket issue 141, there is a compilation error for STM32 if CONFIG_NET and CONFIG_NETDEV_LATEINIT are selected. That was due in part to commit 19e16cb which extended up_netinitialize() with a !defined(CONFIG_NETDEV_LATEINIT) guard but did not add the guard to concrete implementations. I say "in part" because I don't think that the original intent of commit 19e16cb was to enable an alternative initialization of MCU internal Ethernet support but rather to enable support of external Ethernet devices that may have dependencies on, for example, SPI. However, this is still a proper fix to avoid the compilation error that can occur with this combination of configuration options. 2019-01-25 07:21:03 -06:00

db24306435 arch/assertion logic: Fix additional places where the test for an IDLE task is incorrect. It is not invalid in all configurations to check for PID==0. However, the logic fixed in these places lackes sufficient intelligence to find the right stack for the CPU IDLE thread and could still show the wrong stack. 2018-12-18 17:45:46 -06:00

ec9265aa95 arch assertions: Correct duplicated logic from commit dbf01d12b7. Checking for PID == zero is not a valid way to test for the IDLE task in all configurations! This is only true in the single CPU configuration. In multiple CPU configurations, there will be a separate IDLE task for each CPU with a different PID. 2018-12-18 17:35:42 -06:00

dbf01d12b7 Assertions: Identify the running task correctly when dumping task state information. It takes time to switch to the target task after g_readytorun has been modified. If panic/assert happen during this period, the dump will contain the incorrect and confusing information due to the difference between the real running task and the return value of this_task(). This change resolve this problem by adding g_running_task to track the real running task through the context switch. 2018-11-15 07:11:51 -06:00

68e45d0453 Reported by Anonymous in Bitbucket Issue #129:
When MIPS port is built for microMIPS and then loaded as an application, the __start entry point is entered in microMIPS mode, but the CPU core initialization code there misses to set the config3ISAOnExc bit to 1. Subsequently, exceptions are entered in MIPS32 mode, but the code base was built for microMIPS.

22cd0d47fa This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
This makes the user interface a little hostile.  People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header).  A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length.  Instead, we define the packet buffer size then derive the MTU.

The MTU is not common currency in networking.  On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP).  Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes.  So we should be all good and without the recurring 14 byte error in MTU's and MSS's.

Squashed commit of the following:

    Trivial update to fix some spacing issues.
    net/: Rename several macros containing _MTU to _PKTSIZE.
    net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE.  This is not the MTU which does not include the size of the link layer header.  This is the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename the file d_mtu in the network driver structure to d_pktsize.  That value saved there is not the MTU.  The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header.  The MTU does not include the link layer header.

a94e3284b3 syslog: Enable is partial, crippled version of syslog_flush(); arch/: Call syslog_flush() from assertion handling logic. 2018-06-07 16:29:16 -06:00

977d41d519 Based on a change recommended by Mark Shulte:
Signal handlers maybe run with interrupts enabled or disabled, depending on how the task the received the signal was blocked. (i.e.: If sem_wait() is called, then we disable interrupts, then block the currently running task). This could be dangerous, because user code would be running with interrupts disabled.

This change forces interrupts to be enabled in up_sigdeliver() before executing the signal handler calling up_irq_enable() explicitly.  This is safe because, when we return to normal execution, interrupts will be restored to their previous state when the signal handler returns.
