+Subject: [PATCH] Fix build on arm64 architectures with some strict compilers
+
+This patch fixes an issue that occurs on 64-bit architetures under
+strict compiler rules. The code initially checked that the received
+size stored in 'uint64_t' was not bigger than the max value of a
+'size_t' variable, which is legitimate on 32-bit architectures where
+'size_t' variables are stored on 32 bits. On 64-bit architectures,
+this test no longer makes sense since 'uint64_t' and 'size_t' types
+have the same size. The issue is fixed by ignoring this portion
+of code when built for arm64.

+Doing Successive Builds
+-----------------------
+
+If you need to do multiple iterations (while developing/testing) you can use the
+`--rebuild` option instead of `--build` on subsequent iterations. This skips the
+initial check for the freshness of the depends tools. In particular, doing this
+check all the time prevents rebuilding when you have no network access.
+
+
+Local-Only Builds
+-----------------
+
+If you need to run builds while disconnected from the internet, make sure you have
+local up-to-date repos in advance. Then specify your local repo using the `--url`
+option when building. This will avoid attempts to git pull across a network.

moneromooo-monero	912ff6abeb	simplewallet: plug a timing leak As reported by Tramèr et al, timing of refresh requests can be used to see whether a password was requested (and thus at least one output received) since this will induce a delay in subsequent calls. To avoid this, we schedule calls at a given time instead of sleeping for a set time (which would make delays additive). To further avoid a scheduled call being during the time in which a password is prompted, the actual scheduled time is now randomized.	2019-11-02 11:41:30 +00:00
moneromooo-monero	cc2fc0bc3e	epee: allow a random component in once_a_time timeouts	2019-11-01 20:57:59 +00:00
moneromooo-monero	c0f5047878	wallet: reuse cached height when set after refresh Refreshing sets cached height, which is otherwise got by calling get_info. Since get_info is called upon needing to display a prompt after a command has finished, it can be used to determine how much time a given command took to run if the cache timeout lapses while the command runs. Refreshing caches the height as a side effect, so get_info will never be called as a result of displaying a prompt after refreshing (and potentially leaking how much time it took to process a set of transactions, therefore leaking whether we got some monero in them).	2019-11-01 19:00:20 +00:00
moneromooo-monero	f98d9673eb	wallet2: fix is_synced checking target height, not height Target height would be appropriate for the daemon, which syncs off other daemons, but the wallet syncs off the daemon it's connected to, and its target is the daemon's current height.	2019-11-01 19:00:19 +00:00
moneromooo-monero	98cdc84920	wallet: fix another facet of "did I get some monero" information leak We get new pool txes before processing any tx, pool or not. This ensures that if we're asked for a password, this does not cause a measurable delay in the txpool query after the last block query.	2019-11-01 19:00:19 +00:00
moneromooo-monero	69b8aa5a26	wallet2: do not send an unnecessary last getblocks.bin call on refresh The "everything refreshed" state was detected when a refresh call did not return any new blocks. This can be detected without that extra "empty" call by comparing the claimed node height to the height of the last block retrieved. Doing this avoids that last call, saves some bandwidth, and makes the common refresh case use only one call rather than two. As a side effect, it prevents an information leak reported by Tramèr et al: if the wallet retrieves a set of blocks which includes an output sent to the refreshing wallet, the wallet will prompt the user for the password to decode the amount and calculate the key image for the new output, and this will delay subsequent calls to getblocks.bin, allowing a passive adversary to note the delay and deduce when the wallet receives at least one output. This can still happen if the wallet downloads more than 1000 blocks, since this will be split in several calls, but then the most the adversary can tell is which 1000 block section the user received some monero (the adversary can estimate the heights of the blocks by calculating how many "large" transfers are done, which will be sections of blocks, the last of which will usually be below 1000, but the size of the data should allow the actual number of blocks sent to be determined fairly accurately). This timing trick still be used via the subsequent scan for incoming txes in the txpool, which will be fixed later.	2019-11-01 19:00:18 +00:00
moneromooo-monero	2ca057402d	wallet2: do not repeatedly ask for pool txes sent to us This lets a passive attacker with access to the network link between node and wallet perform traffic analysis to deduce when an idle wallet receives a transaction.
